EarthBASE
EarthBASE is a mapping application which provides features in four main areas:
powerful database functions (reads/writes/creates XBASE files; imports/exports
delimited ASCII files), geocodes address locations onto a world map using 5-
digit zip code or latitude/longitude data, graphics file export (.TIF), and data
analysis functions. XBASE files are dBASE compatible database files created
from applications such as dBASE II-IV, FoxPro, Clipper, etc.. A strength of
EarthBASE is its ability to work with large databases while requiring minimal
hardware. EarthBASE is divided into four windows: the globe window, the record
window, the field window, and the file creation window. The main features of
these windows are as follows:
FILE CREATION WINDOW
XBASE files may be created or modified according to a user-specified field
structure. Existing files may have fields added, deleted and/or field names
changed. Multiple files may be joined and records may be appended onto existing
files. Delimited files may be imported and converted to XBASE files.
GLOBE WINDOW
File Import: Opens XBASE files containing up to 35,000 records. EarthBASE
requires 570 Kb to open a 35,000 record file. An XBASE file's structure is
automatically understood as it is loaded. A record is located in the globe
window by using fields containing latitude and longitude data, or secondly, the
first five digits of a zip code from a field containing zip code data, if these
fields are present. All of EarthBASE's features, except record location
visualization, are active if no location data is available.
Record Display Toggle: Records may be displayed based on the following
criteria: all records, all records included by the last query or all records
excluded by the last query.
Output: The displayed contents of the globe window, governed by the record
display toggle, may be sent to the following printers as output: Epson 9 pin,
Epson 24 pin, HP LaserJet and HP DeskJet. The displayed contents may also be
stored to disk as a .TIF graphics image file (TIFF Class B - black and white)
or as an XBASE file. Records are displayed in the globe window and stored in
the XBASE file in the order that they have been sorted in the record window.
Zoom: Zooms in until the width scale of the globe window is 129 feet wide.
Speed: On a 20 MHz 80386 machine, the entire globe is refreshed in less than
1 second if no records are loaded or in less than 6 seconds if 30,000 records
are loaded. Close zoom-in refreshes are near real-time, without records loaded.
Cursor Movement: The arrow keys move the globe in northward, southward,
eastward, and westward directions. The snap mode moves the globe from record
location to record location in the above mentioned directions. A mouse may be
used in place of the arrow keys if the appropriate driver is installed.
Measurement: Measures the direct air distance between any two
points in miles and kilometers.
Count: Counts the number of records within a user-defined circular perimeter.
If the count mode is active during queries in the field window, the query has
the added constraint that the record lie within the chosen perimeter.
Symbol: The user may choose any field, out of which, the globe window's display
symbols for each record is extracted. The font may be scaled to 9 sizes.
Range: The user may choose any numeric field to divide the records into two
ranges (uses two font sizes and colors).
RECORD WINDOW
The record window lists all of the records in the opened XBASE file, row by
row. The user specifies which fields are displayed in the window. Records may
be sorted alphabetically according to their displayed fields or according to
their distances from the globe window's present cursor location. The window
provides a string searching function. The record display toggle functions as
it does in the globe window. The record window list may be printed to a
delimited ASCII file or printer.
FIELD WINDOW
The field window may be entered after selecting a record with respect to its
location in the globe window or with respect to its displayed fields or record
number in the record window. This window views, prints, queries, edits,
creates, copies, sums (field values), and deletes records in the opened XBASE
file. Queried records may be edited, counted, summed (field values), or copied
to a new file. All fields in the opened XBASE file may be queried by example
using '>', '<', and wildcard symbol '*' to constrain the query. The record
display toggle functions as it does in the globe window and is used to create
compound queries.

EarthBASE
1.0 INTRODUCTION
1.1 OVERVIEW
EarthBASE is a mapping application which provides
features in four main areas: powerful database functions
(read/write/create XBASE files; import/export delimited
ASCII files), geocodes address locations onto a world map
using 5-digit zip code or latitude/longitude data, graphics
file export (.TIF), and data analysis functions. XBASE
files are dBASE compatible database files created from
applications such as dBASE II-IV, FoxPro, Clipper, etc.. A
strength of EarthBASE is its ability to work with large
databases while requiring minimal hardware. EarthBASE is
divided into four windows: the globe window, the record
window, the field window, and the file creation window. The
main features are as follows:
FILE CREATION WINDOW
XBASE files may be created or modified according to a
user-specified field structure. Existing files may
have fields added, deleted, and/or field names changed.
Multiple files may be joined and records may be
appended onto existing files. Delimited files may be
imported and converted to XBASE files.
GLOBE WINDOW
File Import: Opens XBASE files containing up to 35,000
records. EarthBASE requires 570 KB to open a 35,000
record file. An XBASE file's structure is
automatically understood as it is loaded. EarthBASE
asks the user to identify fields containing data which
will be used to assign (geocode) a longitude and
latitude to each record. The user is asked to identify
fields containing longitude, latitude and zip code
data.
A record is located in the globe window by using data
from its latitude and longitude fields, or secondly,
the first five digits of a zip code from its zip code
field if these fields are present. All of EarthBASE's
features, except record location visualization, are
active if no location data is available.
Record Display Toggle: Records may be displayed based
on the following criteria: all records, all records
INTRODUCTION 1
EarthBASE
included by the last query or all records excluded by
the last query.
Output: The displayed contents of the globe window,
governed by the record display toggle, may be sent to
the following printers as output: Epson 9 pin, Epson
24 pin, HP LaserJet and HP DeskJet. The displayed
contents may be stored to disk as a .TIF graphics image
file (TIFF Class B - black and white) or as an XBASE
file. Records are displayed in the globe window and
stored in the XBASE file in the order that they have
been sorted in the record window.
Zoom: Zooms in until the width scale of the globe
window is 129 feet wide.
Speed: On a 20 MHz 80386 machine, the entire globe is
refreshed in less than 1 second if no records are
loaded or in less than 6 seconds if 30,000 records are
loaded. Close zoom-in refreshes are near real-time,
without records loaded.
Cursor Movement: The arrow keys move the globe in
northward, southward, eastward, and westward
directions. The snap mode moves the globe from record
location to record location in the above mentioned
directions. A Microsoft compatible mouse may be used
in place of the arrow keys if the appropriate driver is
installed.
Measurement: Measures the direct air distance between
any two points in miles and kilometers.
Count: Counts the number of records within a user-
defined circular perimeter. If the count mode is
active during queries in the field window, the query
has the added constraint that the record lie within the
chosen perimeter.
Symbol: The user may choose any field, out of which,
the globe window's display symbols for each record is
extracted. The font may be scaled to 9 sizes.
Range: The user may choose any numeric field to divide
the records into two ranges (uses two font sizes and
colors).
INTRODUCTION 2
EarthBASE
RECORD WINDOW
The record window lists all of the records in the
opened XBASE file, row by row. The user specifies
which fields are displayed in the window. Records may
be sorted alphabetically according to their displayed
fields or according to their distances from the globe
window's present cursor location. The window provides
a string searching function. The record display toggle
functions in the record window as it does in the globe
window. The record window list may be printed to a
delimited ASCII file or printer.
FIELD WINDOW
The field window may be entered after selecting a
record with respect to its location in the globe window
or with respect to its displayed fields or record
number in the record window. This window views,
prints, queries, edits, creates, copies, sums (field
values), and deletes records in the opened XBASE file.
Queried records may be edited, counted, summed (field
values), or copied to a new file. All fields in the
opened XBASE file may be queried by example using '>',
'<', and wildcard symbol '*' to constrain the query.
The record displayed in the field window may be printed
to a file or printer. The record display toggle
functions as it does in the globe window and is used to
create compound queries.
GENERAL FEATURES
Menu driven, supports Microsoft Compatible Mice.
A password protected entrance.
Device independent graphics support for CGA, MCGA, EGA,
VGA, Hercules, AT&T 6300, and IBM 3270 PC.
Help Screens.

EarthBASE
1.2 GETTING STARTED
Installation should have placed the following files in
a directory:
Ebase.exe: The executable program. Ebase386.exe is
the executable program for 80386 and 80486
machines.
Ebase.ovr: The executable program's overlay file.
Ebase386.ovr is the overlay file for 80386
and 80486 machines.
Citysm.dbf: XBASE file containing several hundred
cities. The file contains state, city,
latitude, and longitude fields.
*.bgi: Graphic drivers.
Litt.chr: Font driver.
Pswd: Password file.
World.dat: Contains location data for the world's
land masses.
Demo.* Various files used by the animated demo
mode of EarthBASE. Type 'ebase demo' to
activate the demo.
Zip5.dat: Contains geocoding data for the first five
digits of zip codes (5-digit accuracy file
received after product is registered).
Help.dat: Help screen text file.
*.doc: Various document text files. The license
document file explains registration
requirements for EarthBASE.
The executable file will work on IBM compatible
computers running under the DOS operating system with at
least 256 KB of RAM. Minimizing buffer and file numbers in
the config.sys file and not using a print spooler, ram disk,
or any other ram resident program will allow more ram to be
allocated to EarthBASE. It is recommended that the computer
have 640 KB of usable RAM (a 1 Megabyte RAM machine) which
would allow EarthBASE to access up to 35,000 XBASE file
records. The *.BGI graphics driver files allow for the
INTRODUCTION 4
EarthBASE
usage of most graphics boards and monitors.
The computer must be started from DOS, which is
provided by the user. Make a backup copy of program files
on formatted blank disks before starting. Copy the contents
of the EarthBASE diskette to a directory on a hard disk.
Type 'pkunzip earthbas.zip' to unarchive the program files.
All of the unarchived files, except the document files,
should be found in EarthBASE's default directory or the
system's environment path. Typing 'ebase' starts EarthBASE.
Typing 'ebase demo' activates a 20 minute animated demo of
EarthBASE's features. EarthBASE searches for its zip code
data file on floppy disk drive B: after having searched on
the hard disk. EarthBASE can function without this data
file but will lack its zip code geocoding capabilities. If
EarthBASE is to be run concurrently from a network server,
EBASE.EXE should be given read-only status (see network
information in the reference section, and network
registration requirements in LICENSE.DOC).
EarthBASE's minimal requirements allow it to be run
from systems with only one low-density floppy disk drive and
256 KB of RAM (i.e. laptops, notebooks, diskless
workstations, etc.). Copy the following minimal files to a
low-density floppy diskette:
EBASE.EXE *EarthBASE EXECUTABLE FILE (or EBASE386.EXE)
EBASE.OVR EarthBASE OVERLAY FILE (or EBASE.OVR)
*.BGI GRAPHICS DRIVER FILES (choose one of the
following)
CGA.BGI ---CGA
EGAVGA.BGI ---EGA or VGA
ATT.BGI ---AT&T
HERC.BGI ---Hercules
PC3270.BGI ---IBM PC3270
PSWD PASSWORD FILE
LITT.CHR FONT FILE
WORLD.DAT WORLD BOUNDARY DATA FILE
HELP.DAT HELP SCREEN TEXT FILE
Place the diskette in drive a:. Notice that the files for
the demo were not transferred to the low-density floppy
diskette so the animated demo can't be run in this
configuration. The 'ZIP5.DAT' file (400 KB), if used,
should be placed on a high-density 5 1/4 inch; a low or
high-density 3 1/2 inch floppy diskette in drive b: or on a
hard disk in the environment's path. An XBASE database
file, if used, must be placed where disk space is available
on a diskette in drive a: or b:; or any location on a hard
disk.

The user must enter the correct password to gain access
to EarthBASE. Until the user has created a password inside
EarthBASE, the user may pass this point by pressing the
ENTER key.
INTRODUCTION 6
EarthBASE
2.0 TUTORIAL
This tutorial will step through the various features of
EarthBASE, as the animated demo does. Key items of the
tutorial are highlighted in bold print. It creates an XBASE
file and finally saves a graphics (.TIF) file displaying and
XBASE file containing queried records. At the DOS prompt,
after typing 'ebase' or 'ebase386', you are asked to enter a
security password. In the main menu's SYSTEM item of the
globe window, you may enter a desired password by choosing
the PSWD menu item. Until this is done, no password is
required at the initial screen. If you like you may get the
feel of adjusting the globe position by using the arrow keys
or a mouse. The Z and ALT-Z keys adjust the zoom level in
or out, respectively. The / key toggles the activation of
the globe or the menu receive keyboard or mouse inputs. We
will return to globe movement later in the tutorial.
EarthBASE contains the following four windows: the
globe window (displays and analyzes XBASE record locations),
the record window (displays selected fields of sorted XBASE
records), the field window (queries and edits the fields of
XBASE records) and the file creation window (creates and
modifies XBASE files based on a user-defined field
structure).
The globe window displays the following: an
orthographic view of the globe, a menu on the right border,
program information along the bottom (free RAM memory,
number of displayed records, decimal longitude and
latitude), and above the just mentioned information a
message and editing window.
The number of displayed records only represents how
many records are currently displayed in the globe window. A
record may not be displayed in the globe window if it was
not successfully geocoded from zip code or latitude/
longitude fields; or the record display toggle (F9 key) has
not allowed it to be displayed. It is possible to have the
number of displayed records equal 0 even though there are
many records in the XBASE file. These non-displayed records
may still be accessed in the record and field windows.
The F1 key presents a help screen in each window of
EarthBASE. Press the F1 key to see a summary of available
functions in the globe window. It should be mentioned at
this point that EarthBASE's default directory may be altered
by selecting DIR in the main menu's SYSTEM item in the globe
window.
TUTORIAL 7
EarthBASE
You may freely adjust the view of the globe by changing
the latitude and longitude of the cursor position in the
center of the globe. Use the arrow keys, a mouse or track
ball to alter the latitude and longitude. The mouse or
track ball driver must be loaded into memory prior to
entering EarthBASE. Use the F4 key to enter the magnitude
of latitude and longitude movement when the arrow keys are
pressed. When a track ball is used, a negative magnitude
will move the globe in the same direction as the track ball
movement. The ALT-F4 key sets the mouse or track ball
sensitivity. You may zoom in your perspective of the globe
by pressing the Z key (nearer by a factor of 2) or out by
pressing the ALT-Z key (further by a factor of 2). Pressing
the C key zooms the globe to the finest screen resolution of
128 feet wide. Pressing the F key zooms the globe to the
coarsest screen resolution of 12500 miles.
If you want to move the cursor location without
redrawing the screen, toggle off globe movement with the M
key. Toggle back globe movement again with the M key. You
can GOTO any location by choosing the GOTO menu item in the
main menu. In the GOTO sub-menu, choose either the POLAR
item to enter a latitude and longitude or the ZIP item to
enter a zip code. The globe will move its cursor location
to data you have entered. If the zip code geocoding file
does not contain a zip code that you have entered, a number
of possible zip codes will be presented to you to choose
from. The ZIPEDT menu item allows you to enter the latitude
and longitude centroid locations of newly assigned zip codes
that are not yet contained in the zip code geocoding file.
The globe is displayed (from fastest refresh to
slowest) in three ways: display no continent boundaries,
display continent boundary outlines or fill in the continent
boundaries. The F3 key is used to toggle these modes.
Displaying continent boundaries is not always necessary if
you are zoomed in with record locations displayed on the
screen. Globe movement will interrupt any screen drawing
unless this is toggled off with the F7 key.
Press the / key to activate the globe window's main
menu (the / key toggles whether the globe or the menu is
currently active in the globe window). Then use the up and
down arrow keys to place the cursor on the FILE menu item.
Press the ENTER key to choose this menu item. In this sub-
menu, choose the CREATE menu item to enter the file creation
window. This window allows you to create XBASE files with a
unique field structure. Press the F1 key to see a short
description of the file creation window.
TUTORIAL 8
EarthBASE
The left most column lists the field names of an
existing loaded field structure. In the columns to the
right you may alter these field names, specify field types
and specify field lengths. If the field type is numeric
(N), you are asked to enter the number of decimal places.
You may create a unique field structure or load the field
structure of an existing XBASE file. In order for an XBASE
file's records to be geocoded in the globe window, an XBASE
file's field structure must contain a zip code field or
latitude and longitude fields. Field names must be spelled
as shown the overview section above. You can load an XBASE
file's field structure by moving the cursor down to the
horizontal menu bar and pressing the FILE menu item. Then
choose the LOAD menu item and type in a file's name. The
wildcard (*.dbf) name may be used to open up the directory
utility to show all matching files in the default directory.
In the directory utility you may select a filename by
highlighting the filename and pressing the ENTER key or
escape out of the window by pressing the ESC key.
Examine the field structure of this loaded XBASE file.
You may add, delete or modify the characteristics of
existing fields. Choose the ROW menu item and then either
the INSERT, DELETE or COPY menu items to insert blank field
rows, delete field rows, or copy a field row of the existing
field structure. If you like you may load the field
structures of multiple XBASE files and append them to the
fields already contained in the field window. The main menu
also includes the PRINT menu item which allows you to print
the field structure to a file or printer.
When the field structure is completed, you should save
the structure by saving it as an XBASE file. Choose the
FILE menu item in the main menu and then the SAVE menu item
in the sub-menu. You may save it as a new file with no
records by not entering a filename when you are asked to
enter a filename from which records will be extracted from
and existing file. If you do enter a filename of an
existing file, non-deleted records will be copied from the
existing file to a second file you specify if there are like
fields in the existing file and the field structure in the
file creation window. Matching fields must have exact field
names and type, but need not have the same field length.
If the second file already exists, you may APPEND the
extracted file's records to the second file. Records from
multiple existing files may be extracted giving you the
ability to JOIN multiple databases. The multiple databases
should however contain identical records.
TUTORIAL 9
EarthBASE
The extracted records may be contained in a delimited file,
but the delimited fields must match the field structure in
the field window by order and type. This is the method of
importing a delimited file into XBASE file format so that it
may be used in EarthBASE. Create the delimited file's field
structure in the file creation window and then save the
delimited file's records in an XBASE file.
It is possible to edit the field structure of an
existing file by loading its field structure, editing the
structure, extracting records from the existing file and
saving the new structure to the same existing file. You may
clear the field structure in the file creation window by
loading a new file or by choosing the CLEAR menu item in the
FILE sub-menu. We will now exit out of the file creation
window back to the globe window by pressing the ESC key
(press several times depending on the current menu level).
In the globe window, you may now open the file you just
created/modified in the file creation window or any file by
choosing the OPEN menu item in the FILE sub-menu. Again the
directory utility is available for wildcard filenames.
Opening a file clears from memory a currently opened file as
does choosing the CLEAR menu item of the FILE menu item. In
the opening process, EarthBASE asks you to identify fields
containing data which will be used to assign (geocode) a
longitude and latitude to each record. You will is asked to
identify fields containing longitude, latitude and zip code
data. If the file contains a zip code field or latitude and
longitude fields and each record contains data in these
fields, the record will be geocoded onto the surface of the
globe.
When a file is opened, each record's location data is
loaded into memory. This speed's the globe drawing process
and is also the reason why available memory determines how
many records an opened file may contain. If a file is
shared on a network where other users or processes are
continually altering record's location data, you may want to
update the location data in memory by pressing the ALT-F1
key. This forces EarthBASE to read the location data from
disk until the ALT-F1 key is pressed again. This, of
course, slows the globe drawing process.
Now that a file is opened, we can now use the record
window's GOTO function to move directly to the location of a
specific record. Press the F10 key to enter the record
window. In the record window, the cursor highlights the
record nearest to the globe window's current cursor
location. Use the up and down arrow keys, the PAGEUP and
TUTORIAL 10
EarthBASE
PAGEDN keys and/or the CTRL-PAGEUP and the CTRL-PAGEDN keys
to move the cursor to a record of choice. Then press the
F10 key to return back to the globe window at the location
of the selected record. If you had pressed the ESC key in
the record window, you have returned back to the globe
window at its original location prior to entering the record
window. The record window will be discussed further later
in the tutorial.
Choosing the RECORD item in the globe window's main
menu brings up a sub-menu of items which act on records.
You may edit, delete, create, copy or move a record after a
record or location has been selected. All of the menu items
except the delete function loads the field window with
record of choice or with a new record with the latitude and
longitude fields filled with the current cursor location.
After editing the record's fields, you must press the F10
key to save the record to the opened XBASE file. Other
functions available in the globe window will be discussed
later. Press the ESC key to return back to the globe
window. A short cut to entering the field window is to
press the F5 key. The field window will contain the record
closest to the globe window's current cursor location.
In the globe window, if you want the cursor to move to
the location of a record, it may take some time to do this
with the arrow keys. By pressing the F2 key, the snap mode
is activated so that the cursor location snaps from record
location to record location. If you press the F2 key again,
the snap mode is deactivated. In addition to the 'x'
representing a record location in the globe window, you can
also select any field in the opened file from which each
record's display symbol will be extracted. Choose the
SYMBOL item in the globe window's main menu. A field select
window is presented to you listing all of the fields in the
opened file. Fields which are currently displayed in the
record window are highlighted. Choose one of the fields by
placing the cursor on it and pressing the ENTER key. You
may escape out of the window by pressing the ESC key.
The first non-blank character of the selected symbol
field is now displayed for all records. Pressing the F6 key
causes the entire field contents to be displayed for each
record. Pressing the F6 key again causes only one character
to be displayed. Displaying only one character will refresh
the screen faster. Choosing another display field or
deactivating a display field requires that you choose the
SYMBOL menu item again. Pressing the F4 key allows you to
enter a font size value from 1 to 9.
TUTORIAL 11
EarthBASE
The RANGE item in the globe window's main menu allows
you to choose a numeric field in the field select window
which will be used to divide all records into two ranges.
Only numeric fields are displayed in the field select
window. Once a field is selected, you are asked to enter a
numeric value to divide the records based on the selected
field. Records whose field value is larger than the
dividing value will have their display items colored red and
at one font size larger than the default font chosen with
key F4. Records whose field value is smaller than or equal
to the dividing value have their display items displayed at
one font size smaller than the default font size. Choosing
another range field or deactivating a range field requires
that you choose the RANGE menu item again. Please leave the
range field active during the rest of the tutorial.
You may measure the direct air distance between any two
points by choosing the MILES item in the globe window's main
menu. Once the base location is chosen, use arrow keys,
snap mode and/or GOTO functions to move the cursor to the
desired locations. You may repeatedly measure new distances
from the original base location prior to pressing the ESC
key to stop the measuring function. This mode may not be
active if the M key has been pressed to freeze the globe
movement.
You may count the number of records located in a chosen
radius by choosing the COUNT item in the globe window's main
menu. Once the base location is chosen, use arrow keys,
snap mode and/or GOTO functions to move the cursor to the
desired locations. In this case, the cursor is the
intersection of the radius and the circle. The message
window displays the radius of the circle and the number of
displayed records contained in the circle. You may
repeatedly count the number of records in a new circle size
from the original base location prior to pressing the ESC
key to stop the measuring function. This mode may not be
active if the M key has been pressed to freeze the globe
movement. Please leave the count mode active during the
rest of the tutorial.
Let's return to the record window again by pressing the
F10 key. The record window lists all of the non-deleted
records in the opened XBASE file with the record number
along the left border. If a range field is active and a
record's field value is greater than the range dividing
value, the record number will be colored red for color
monitors and reversed color for monochrome monitors. If the
globe window's count mode is active the displayed fields of
records contained in the circle have their colors reversed.
TUTORIAL 12
EarthBASE
Press the F1 key to see a summary of available functions in
the record window.
By default, the record window displays fields, if
available, containing latitude, longitude, zip code, user-
specified range and user-specified symbol data. By pressing
the F8 key, you may choose your own display fields in. The
F7 key returns the displayed fields to the default fields.
Pressing the F2 key allows you to search for a string. The
horizontal menu along the bottom allows you to enter the
field window similar to using the record menu in the globe
window. The PRINT menu item prints the record window
contents to a file or to a printer. Move the cursor down to
the menu and choose the EDIT menu item.
After you choose a record, you enter the field window.
If a range field is active and a record's field value is
greater than the range dividing value, the record number on
the top screen row will be colored red for color monitors
and reversed color for monochrome monitors. If the globe
window's count mode is active the top screen row states
whether or not the record is contained in the circle. The
up and down arrow keys moves the cursor from field to field.
The PAGEUP and PAGEDN keys and/or the CTRL-PAGEUP and the
CTRL-PAGEDN keys loads previous or later records into the
field window. By pressing the left arrow key or beginning to
type activates the editing of a specific field until the
ENTER key is pressed. The field window's contents can be
printed to a file or printer by pressing the ALT-F9 key.
The F7 key creates a new record without leaving the field
window. The F8 key copies the present field window contents
to a new record without leaving the field window. Press the
F1 key to see a summary of available functions in the field
window.
The field window's main functions are to edit the
fields of a record and to query/search records. The F2, F3,
and F4 keys allow you to search for records whose
appropriate field (cursor-highlighted field) contains string
which you specify. The F2 key allows you to edit each
matched record. Remember to press the F10 key to save the
record contents before proceeding to a new record. The F3
key counts matched records and the F4 key copies matched
records to an XBASE file which you specify. The F5 key sums
the appropriate field (cursor-highlighted numeric field)
values of all records. The F6 key writes a string which you
specify to the appropriate field (cursor-highlighted field)
of all records.
The ALT-F2, ALT-F3, ALT-F4, ALT-F5, and ALT-F6 function
TUTORIAL 13
EarthBASE
keys are query by example function keys. They perform the
same function as their non-ALT counterpart keys above except
that in order for a record to match, all of its fields must
match all of the field window fields exactly. The special
query symbols '<', '>', and '*' are also used to modify the
matching constraints when the ALT function keys are used.
If a string in a field window field is led by a '<' or '>',
a record's field string will only match if it is less than
or greater than the field window's field string following
the '<' or '>' symbol. Matches are not case sensitive
(whether or not a character is capitalized). Spaces are not
ignored in the field window's field nor in a record's field.
If the field window's field contains the '*' wildcard
symbol, only the characters to the left of the '*' symbol
are used for matching. Therefore if a field in the field
window contains an '*' as the first character, the field
will not be used in rejecting records. It is suggested that
you save 'query' record templates as records in the XBASE
file for commonly executed queries.
If the count mode is active in the globe window prior
to entering the field window, all record matches must
satisfy the added constraint that the record lie within the
user-specified circular perimeter. This constraint is valid
for all ALT and non-ALT keys. Please perform a query at
this time using one of the ALT function keys. The rest of
the tutorial assumes that a query has been performed. By
toggling the F9 key, you dictate whether the field window
accesses all records, only records included by the last
query or only records excluded by the last query. In this
way you may perform compound queries by basing new queries
on the results of past queries. After each query the F9
mode is set to accessing all records.
Press the ESC key now to return to the record window.
By default the record window lists the records in the order
of their record numbers. Press the F5 key to sort the
displayed fields alphabetically. Remember that you can
specify which fields are displayed. Press the F6 key to
sort the records according to their distance to the globe
window's current cursor location.
At this point, the record window displays the sorted
records in addition to information on each record's
relationship to the range field and count mode. Additional
information may be gleaned by pressing the F9 key. This
toggles whether all records are displayed, all records
included by the last query are displayed or all records
excluded by the last query are displayed. Press the ESC key
to return back to the globe window.
TUTORIAL 14
EarthBASE
At this point just as in the record window, the globe
window displays the record locations in addition to
information on each record's relationship to the range field
and count mode. Again, additional information may be
gleaned by pressing the F9 key. Press the F9 key to see the
records included by the last query. Press it again to see
the records excluded by the last query. Notice that the
count mode only counts the number of records displayed
inside the circle. The number counted will therefore differ
based on the status of the F9 key.
As an end of the tutorial, we will now show how to save
the globe window's screen contents to a graphic file or the
displayed fields to an XBASE file. In the globe window's
main menu, choose the OUTPUT menu item. In the sub-menu,
choose the .TIF menu item. The F9 key will determine which
records are displayed when the TIFF graphics file is saved.
Choose the .DBF menu item to save the displayed records in
an XBASE file. Remember that the F9 key will determine
which records are displayed and therefore which records are
saved in the XBASE file. The displayed records are also
saved in the order in which they have been sorted in the
record window.
Most of EarthBASE's functions have now been discussed.
Refer to other sections of the manual for further
information.
TUTORIAL 15
EarthBASE
3.0 GLOBE WINDOW
The purpose for this window is to display the global
locations of records contained in the opened XBASE file.
Upon entering this window the user is presented with an
orthographic view of the world, a menu along the right
border, and an information window along the bottom as seen
on the manual's front cover. The information window lists
from left to right the amount of free RAM, the number of
XBASE records displayed in the globe window, and the
latitude and longitude location of the screen cursor. The
information window also displays textual information and
asks for keyboard input at appropriate times. The F1 key
displays a help screen listing the available function keys.
All of the function keys described in this section are also
found in the globe window menu tree's toggle, system and
goto menu items.
The number of displayed records only represents how
many records are currently displayed in the globe window. A
record may not be displayed in the globe window if it was
not successfully geocoded from zip code or latitude/
longitude fields; or the record display toggle (F9 key) has
not allowed it to be displayed. It is possible to have the
number of displayed records equal 0 even though there are
many records in the XBASE file. These non-displayed records
may still be accessed in the record and field windows. The
largest record number in the XBASE file may be found as the
last row number in the record window.
This section will describe the features of the globe
window, the menu items, and the command keys. The field
window may be entered directly by pressing the F5 key or by
choosing the appropriate menu item under the RECORD menu.
The record window may be entered directly by pressing the
F10 key. When the F5 or F10 key is pressed, the field
window contains and the record window highlights the record
nearest to the globe window's current location.
3.1 FEATURES
Initially the globe's continent boundaries and equator
are outlined. The user's location is at the cursor location
in the center of the globe. By pressing the F3 toggle key
the user can cause EarthBASE to display, not display or fill
in the boundaries of the continents. Pressing the Z key
will cause the user's perspective to zoom in twice as close.
The user may zoom in seven times. Pressing the C key moves
GLOBE WINDOW 16
EarthBASE
the window directly to the nearest zoom level. To zoom out
twice as far, press the ALT-Z key combination. Pressing the
F key moves the window directly to the furthest zoom level.
The right arrow key moves the cursor location eastward.
The left arrow key moves the cursor location westward. The
up arrow key moves the cursor location northward. The down
arrow key moves the cursor location southward. If an XBASE
file is open and the user has toggled on the snap mode (F2
key), the arrows keys will move the cursor to the nearest
northern, southern, western, or eastern record. In this
case the cursor latitude and longitude is exactly that of
the record. Cpu time may be saved by pressing the M key.
In this mode the globe is frozen and the cursor moves on the
globe up to the globe's current horizon. Pressing the M key
again freezes the cursor and frees the globe for movement.
A Microsoft compatible mouse may be used in place of
the arrow keys if the user has installed an appropriate
device driver. The magnitude of movement in degrees is
determined by the user. By pressing the F4 key, one can
specify the movement amount, in degrees, at the present zoom
level. If the user zooms in once, the movement value is
divided by 2. If the user zooms out once the movement value
is multiplied by 2. The cursor movement value is limited to
between 0.001 and 45.0 degrees. By pressing the CTRL key
while pressing the right or left arrow keys, the cursor
movement is multiplied by 10. The PAGEUP and PAGEDN keys
replicate the up and down keys, but multiply the cursor
movement by 10. If an up or down command is given that
would require cursor movement past the north or south pole,
the cursor will position itself at the north or south pole.
Pressing the HOME key moves the cursor location to
latitude = 0 degrees and longitude = 0 degrees. Pressing
the END key moves the cursor location to latitude = 0
degrees and longitude = 180 degrees. Pressing the INS key
moves the cursor location to latitude = 0 degrees and
longitude = -90 degrees. The menu item GOTO allows the user
to specify a longitude and latitude or zip code to which the
globe window will be moved directly (the record window
allows the user to GOTO a specific record location - F10
key). Pressing the / key deactivates the globe movement and
activates the menu. The globe is not redrawn until the
keyboard buffer is empty. The redrawing process may be
interrupted by a keyboard input. The cursor in the center
of the globe blinks when EarthBASE is idle.
If an XBASE file has been opened and the record is
valid for display, a '+' or user-defined ascii symbol will
GLOBE WINDOW 17
EarthBASE
be displayed on the globe at its latitude and longitude
location. The records are displayed in the order that they
have been sorted in the record window.
If a record's displayed screen pixel location coincides
with the cursor's screen pixel location, its representative
fields (chosen in the record window) will be shown in the
information window. If more than one record's displayed
screen pixel location coincides with the cursor's screen
pixel location, only one record's representative fields will
be displayed. In this case the user must zoom in closer to
differentiate between the various record locations. If the
user wants a record's representative fields to appear in the
information window and the record's location is near the
cursor location, there are two methods to cause this to
happen. The user may use the arrow keys to move the
record's screen pixel location or the user may zoom out to
cause this to happen.
When a file is opened, EarthBASE asks the user to
identify fields containing data which will be used to assign
(geocode) a longitude and latitude to each record. The user
is asked to identify fields containing longitude, latitude
and zip code data. If latitude and longitude data is not a
available, the first five digits of a zip code in a zip code
field will be used to assign a general location if it is
available. This location data is stored in memory and no
longer read from the disk to speed the drawing process. If
the user alters the location data for a record, the data in
memory is updated. If other users on a network or other
processes alter the databases location data, EarthBASE is
not aware of these changes and does not update the data in
memory. In these cases, the user should use the ALT-F1 key
in the globe window to force the reading of location data
from the disk. See the Reference section for a discussion
on networking issues.
The following menu item and function key sections
describe the many features of the globe window. The user
may measure distances between two points, count the number
of records in a user-defined circular perimeter and choose
the field out of which the display symbol will be extracted.
The F6 key toggles whether the complete display symbol is
displayed or only the first character. The F9 key toggles
which records are displayed in the globe window based on the
following criteria: all records, all records included by
the last query or all records excluded by the last query.
XBASE and graphics (.TIF) files may be saved containing the
current globe window contents. For a summary of the globe
window's main features, please see the overview subsection
GLOBE WINDOW 18
EarthBASE
of the introduction section above.
3.2 MENU ITEMS
The menu is activated by pressing the / key. In order
to deactivate the menu and activate world movement, the user
should press the / key again. The user traverses the menu
by pressing the up and down arrow keys. The user chooses a
menu item by pressing the ENTER key after it is highlighted.

further in the menu discussion below. Function keys which
provide the same feature as a menu item follow the menu item
in parentheses.
GLOBE WINDOW 19
EarthBASE
File:
a) Open: Opens an XBASE file and loads location
data for all non-deleted records. If
another file was already open, it is
closed and its data cleared from memory.
When the Open menu item is chosen, the
file name of the last opened file is
presented to the user. He/she may edit it
or accept it by pressing the ENTER key.
If a file contains more records than
memory allows to be accessed, the user may
still work normally with the records which
are accessed into memory. In the low
memory case however, the user may not add
additional records to the file. In the
XBASE file opening process, EarthBASE asks
the user to identify fields containing
data which will be used to assign
(geocode) a longitude and latitude to each
record. The user is asked to identify
fields containing longitude, latitude and
zip code data.
b) Clear: Closes an open file and clears its record
data from memory.
c) Create: Enters the file creation window.
GLOBE WINDOW 20
EarthBASE
Record Menu: Excepting the create option, all items in
this menu act on the user-specified record
whose displayed fields are found in the
information window.
a) Delete: The user may delete the chosen record.
The process may be repeated until the user
presses the ESC key.
b) Copy: The user may copy a chosen record to a
second cursor location. The field window
is opened to the user with the new
location found in longitude and latitude
fields if present. If only a zip code
field is present, it is the user's
responsibility to enter the correct zip
code. If this is not done, the location
information will be lost for that record
when the file is closed.
c) Move: The user may move a chosen record to a new
cursor location. The field window is
opened to the user with the new location
found in longitude and latitude fields if
present. If only a zip code field is
present, it is the user's responsibility
to enter the correct zip code. If this is
not done, the location information will be
lost for that record when the file is
closed.
d) Edit: The user may edit the chosen record in the
field window.
e) Create: The user may create a record in the field
window at the current cursor location.
Goto:
a) Create: Enters the file creation window.
b) Field: Enters the field window. (F5 key)
c) Record: Enters the record window. (F10 key)
d) Zipedt: Allows the user to edit or add location
data for five digit zip codes to the zip
code data file (Zip5.dat). This allows
the user to keep the zip code data file
GLOBE WINDOW 21
EarthBASE
current as new zip codes are assigned by
the U.S government. Registered EarthBASE
users will be notified of official updates
to Zip5.dat, which may be purchased twice
a year.
e) Polar: Moves the globe position to a user
specified latitude and longitude.
f) Zip: Moves the globe position to a user-
specified five digit zip code location.
If the zip code data file does not contain
location data for the zip code, a window
is presented to the user listing the
nearest zip codes which have location data
assigned to them. The user chooses a zip
code by highlighting it with the cursor
and pressing the ENTER key. The user may
also press the ESC key to exit the window.
If the user knows the location to a newly
assigned zip code, he/she may enter that
information in the zipedt menu item
previously described above.
Incre: Sets the cursor movement value in degrees.
The value is automatically halved or
doubled as the globe is zoomed in or out,
respectively. A negative value is
allowable and recommended for use with
track balls. The globe will then move as
the track ball moves. (F4 key)
Output:
Outputs the currently displayed contents
of the globe window, governed by the F9
key (record display toggle).
a) Printer:
1) Epson 9p: Sends the globe window as printer
output to an Epson 9 pin printer.
2) Epson24p: Sends the globe window as printer
output to an Epson 24 pin printer.
3) HPLasJet: Sends the globe window as printer
output to a HP LaserJet printer.
4) HPDeskJt: Sends the globe window as printer
GLOBE WINDOW 22
EarthBASE
output to a HP DeskJet printer.
b) .TIF: Saves the globe window in a .TIF graphics
formatted file (TIFF Class B - black and
white). Printer output may be created by
importing the .TIF file into an
application (word processor, desktop
publisher, paint program, etc.) which
accepts such a file. Such an
application's printer capabilities would
then be used to output the image to a
printer.
c) .DBF: Saves the displayed records in an XBASE
file. Records are stored in the order in
which they have been sorted in the record
window.
Toggle:
a) Snap: Toggles the snap mode. When the mode is
active, the arrow keys move the cursor to
the nearest northern, southern, western,
or eastern record location. (F2 key)
b) Display: Toggles the following globe drawing
methods: outlines the continent
boundaries, only draws record locations
and fills in the continent boundaries. To
speed the filled continent boundary mode,
it is assumed that no water boundary is
present at the 25 mile wide screen zoom
level or nearer. (F3 key)
c) Symlen: Toggles the record's symbol string length
from one character to the entire field
length. The globe window refreshes itself
faster if only the first character is
displayed. (F6 key)
d) Skip: Toggles whether refreshing of the screen
is interrupted by user inputs at the
keyboard or by a Microsoft compatible
mouse. As EarthBASE executes on ever
faster machines it may be better to allow
the screen to fully draw itself before
accepting the next user input. (F7 key)
e) DQuery: Toggles the displaying of records
according to the following: all records,
GLOBE WINDOW 23
EarthBASE
all records included by the last query or
all records excluded by the last query.
This function is only available if the
database has not been altered since the
last query. When the database has been
altered, the toggle reverts back to the
display all records mode. (F9 key)
DSource: Toggles whether address location data is
constantly read from the disk or read from
its stored location in memory. If the
address location data fields in the opened
XBASE file are not altered by other users
in a network or other processes, there is
no need to read the data constantly from
the disk. Reading the data from the disk
slows the drawing process. EarthBASE is
aware when its own user alters address
location data and updates the data stored
in memory. See the Reference section for
a discussion on networking issues.
(ALT-F1 key)
g) Freeze: Toggles whether the globe (redraws) or the
cursor (no redraw) moves when an arrow key
is pressed or the mouse is moved. CPU
time is saved by not redrawing the globe.
(M key)
h) Centroid: Toggles whether zip code centroids are
displayed. The user specifies the range
of zip codes to be displayed. (P key)
System:
a) Shell: Calls the DOS operating system without
permanently leaving EarthBASE. Once in
the DOS SHELL the user can execute any
DOS command. The user reenters
EarthBASE by typing EXIT. (ALT-D key)
b) Font: Sets the globe window font size (1 - 9).
Text is only displayed in the globe window
when a display symbol field has been
chosen. (F8 key)
c) Mouse: Sets mouse and track ball movement
sensitivity. A larger number entered at
the prompt causes less sensitivity to
input device movement. (ALT-F4 key)
GLOBE WINDOW 24
EarthBASE
d) Dir: This menu item allows the user to alter
the default drive and/or directory. The
present default directory is presented to
the user for modification. After editing
the default drive and/or directory and
pressing the ENTER key, the default
directory will be changed to that shown if
no error has occurred.
e) Pswd: This menu item allows the user to alter
EarthBASE's password. The current
password is presented to the user for
editing or replacement. The password is
saved in the password file 'pswd'. The
file 'pswd' must be found in EarthBASE's
default directory or DOS's environment
path.
Miles: This menu item allows the user to
determine the shortest direct air distance
between a first and second location in
miles and kilometers. A line is drawn
between the two locations and the distance
is shown in the information window. The
user may continue to measure a new
distance to a new second location until
the ESC key is pressed. The cursor will
then remain at the last second location
chosen.
Count: This menu item totals the number of
records contained in a user-specified
circular perimeter. The arrow keys move
the intersection point of the circle with
its radius. The number of encircled
records is shown in the information
window. The user may exit the count mode
by pressing the ESC key. The field and
record windows act differently if they are
entered while the count mode is active.
This will be explained in the field and
record window sections of the manual.
Range: By choosing the range menu item, the user
may choose any numeric field which will be
used to separate the records into two
ranges. A window is presented to the user
listing the opened XBASE file's fields
from which the range field is chosen.
GLOBE WINDOW 25
EarthBASE
Fields highlighted in this window are
those currently displayed in the record
window. The user chooses a field by
highlighting it with the cursor and
pressing the ENTER key. The user may also
choose 'NONE' to deactivate the range
function. The user may press the ESC key
to exit the menu item.
After a field has been chosen, the user is
asked to enter the numeric value used to
divide the two ranges. If a record's
range field value is greater than the
dividing value, its display symbol text
(display field must be active) is
displayed with a font size one step larger
than the default size, while the other
records are displayed with a font size one
step smaller than the default size. In
addition, if a color monitor is used,
records whose range field value is greater
than the dividing value will have its
display symbol text (display field must be
active) and locator marker '+' colored
red.
Symbol: By default, EarthBASE uses a '+' as the
display symbol for a record. By choosing
the symbol menu item, the user may choose
any field whose contents will be used for
the display symbol of each record. A
window is presented to the user listing
the opened XBASE file's fields from which
the symbol field is chosen. Fields
highlighted in this window are those
currently displayed in the record window.
The user chooses a field by highlighting
it with the cursor and pressing the ENTER
key. The user may also choose 'NONE' to
deactivate the field symbol function and
revert back to the '+' symbol. The user
may press the ESC key to exit the menu
item.

4.0 FILE CREATION WINDOW
The user enters this window by choosing its menu item
in the globe window. This window creates XBASE files with
user-defined fields. The user may create a field structure
or load a field structure from an existing XBASE file and
then modify it. The user may load the field structures of
multiple XBASE files and append them to the fields already
contained in the field window (useful for joining data from
multiple XBASE files). The user may save the field
structure as a new file with zero records or may copy like
fields (original field name to new field name as mentioned
below) from the records of an existing file into a new file.
All marked-for-deletion records are purged as records are
moved from an existing file to a new file. If the new file
already exists and has a field structure matching that in
the file creation window (field structure must have been
loaded from the existing file and be unchanged), the user
may append a file's records to the records of the existing
file. Records may be extracted from multiple files. In
this way the user may join multiple databases. Multiple
databases should however contain identical records. The
extracted records may be contained in a delimited file, but
the delimited fields must match the field structure in the
field window by order and type.
The user should delete all rows from a loaded field
structure for data not to be moved from an original field
name to the new file. A field in the new file will be empty
if the original field name in the field structure is empty
or not found in the existing 'from' file. The existing
'from' file need not be the file from which a field
structure was loaded.
In summary, the following steps are taken in creating a
file:
1. The user creates the field structure of the XBASE
file to be created by entering the fields in the
file creation window or loading/editing the field
structure from existing XBASE files.
2.The user saves the XBASE file to be created. If
this file already exists and has a field structure
matching that in the file creation window (field
structure must have been loaded from the existing
file and be unchanged), the user is asked if records
should be appended to this file.
FILE CREATION WINDOW 29
EarthBASE
3.The user is asked from which source file records
should be copied to the new file (or appended to an
existing file). If no source file is given, an
empty file is created with the desired field
structure.
4.After the records of a source file have copied to
the new file, the user is repeatedly asked if
records from additional source files should be
copied (joined) to the new file. If the user
answered yes to the 'append records' question, this
mode remains true for the remainder of the save
operation. If the user does want to join records
from many XBASE files into one XBASE file, the field
structures from these XBASE files should have been
loaded into the file creation window and edited as
desired.
The column arrangement of the file creation window's
spreadsheet is set and not adjustable by the user. The left
most column contains the original field names of a loaded
field structure (limited to 11 characters and left-
justified). The columns to the right allow the user to
modify the field names to be used in the saved field
structure, the field type (limited to 1 character: C =
character, N = numeric, L = logical, D = date) and the field
length (limited according to field type). If the field type
is numeric, the user is requested to enter the number of
decimal places. If the number of decimal places the user
enters are too many for the field length, EarthBASE will
override the decimal place number and give the maximum
allowed. The row number is found along the left border.
The F1 key displays a help screen listing the available
function keys.
For the user's information, the XBASE standard
specifies the following:
Maximum record size (bytes) = 4000 (.dbf file)
Maximum number of fields in record = 255 (dBASE IV)**
= 128 (dBASE III)
= 32 (dBASE II)
Maximum field name length = 11
** EarthBASE allows a maximum of 255 fields in a record.

The user maneuvers in the spreadsheet by using the
following keypad keys, in addition to the arrow keys: the
PAGEUP and PAGEDN keys move the cursor position up or down
by 19 rows; the HOME, INS and END keys return the cursor to
top, middle and last rows, respectively. To edit a cell at
which the cursor resides, the user simply begins typing.
4.1 MENU ITEMS
A menu lies at the bottom of the data window. Pressing
the / key moves the cursor to the menu bar. The user
traverses the menu by pressing the right and left arrow
keys. The user chooses a menu item by pressing the ENTER
key after it is highlighted.
Figure 2 displays the menu tree of the file creation
window:

The window may be exited by pressing the ESC key at the
main menu. Pressing ESC at a lower menu will return the
user to the main menu. Pressing ESC will allow the user to
escape from a menu item once its action is in progress.
File:
a) Load: Loads in the field structure of an XBASE
file. When the load menu item is chosen,
the file name of the last loaded file for
FILE CREATION WINDOW 31
EarthBASE
this window is presented to the user.
He/she may edit it or accept it by
pressing the ENTER key.
b) Save: Asks the user for the file name of a new
XBASE file into which the file creation
window's present field structure will be
saved.
The user is then asked for the name of an
XBASE file from which data will be
extracted and placed in the new file. As
a default, the file name of the loaded
field structure is presented to the user,
which he/she may alter. Only data from
fields matching the original field names
will be transferred to the new file. If
the user specifies no second file name the
new file will have no records. If the new
file already exists, the user has the
option of appending the transferred
records to the existing file. Records may
be extracted from multiple existing files.
In this way the user may join multiple
database. The multiple databases should
however contain identical records.
The transferred records may be contained
in a delimited file, but the delimited
fields must match the field structure in
the field window by order and type.
EarthBASE only recognizes delimited files,
as such, if its extension is '.TXT'. The
user may specify the delimiting character
found in the delimited file. This is the
method of importing a delimited file into
XBASE file format so that it may be used
in EarthBASE. Create the delimited file's
field structure in the file creation
window and then save the delimited file's
records in an XBASE file.
c) Clear: Clears the spreadsheet of the current
field structure information.
Row:
a) Insert: Inserts a blank row at the location of the
cursor and shifts all lower rows down one
row.
FILE CREATION WINDOW 32
EarthBASE
b) Delete: Deletes the contents of one row at the
cursor location and shifts all lower rows
back one row. This process is repeated
until the user presses the ESC key.
c) Copy: Copies the contents of a set of rows to a
second row position. The original field
name status (empty or filled) is retained
in the copying process.
Print: Prints the contents of the spreadsheet to a

5.0 RECORD WINDOW
The user enters the record window by pressing the F10
key in the globe window, if an XBASE file is open. This
window, in a spreadsheet format, contains the list of
records from the currently opened XBASE file and displays
user-selected fields for each record. Upon entering the
record window, the cursor highlights the record nearest to
the globe window's cursor location. If the globe window is
in the count mode when the record window is entered, records
located in the user-defined perimeter have their fields
displayed in reversed color. If the globe window is in the
range mode and the range field causes a record's globe
window display symbol to be displayed in red (or larger
font), its record number will be displayed in red (or
reversed color) in the record window. The user may enter
the field window after choosing the appropriate record
window menu item and record. The F1 key displays a help
screen listing the available function keys. All of the
function keys described in this section are also found in
the record window menu tree items.
5.1 FEATURES
The default displayed fields (F7 key), if available,
contain the following data from left to right are:
latitude, longitude, zip code, user-specified range and
user-specified symbol data. The display symbol is a '+' if
no display symbol field has been chosen in the globe window.
If no display symbol is shown for a record, that record was
not successfully geocoded to a location on the globe. The
user may also choose which fields will be displayed in the
record window using the F8 key. The F9 key toggles whether
records are displayed based on the last query in the field
window.
The record number is displayed along the left border.
Record numbers which are skipped are record's which are
marked for deletion in the opened file. The records may be
sorted by alphabetizing the record's displayed fields or
sorting the records according to their distance to the globe
window's current cursor location. The user may search for
specific strings or record numbers. The record list may be
printed to a file or printer.
The cursor moves in the window by using the arrow keys
and other keypad keys. The PAGEUP and PAGEDN keys moves the
cursor position up or down by 19 rows (190 rows if CTRL key
FILE CREATION WINDOW 34
EarthBASE
also pressed). Pressing the HOME key returns the cursor to
the first row, while the END key moves the cursor to the
last row containing information. The INS key moves the
cursor to the middle row containing information. The F10
key returns EarthBASE to the globe window at the location of
the cursor highlighted record. If the user presses the ESC
key the globe window returns to its former location.
5.2 MENU ITEMS
A menu lies at the bottom of the data window. Pressing
the / key moves the cursor to the menu bar. The user
traverses the menu by pressing the right and left arrow
keys. The user chooses a menu item by pressing the ENTER
key after it is highlighted.

record in the field window.
d) Delete: The user may delete a chosen record. The
process is repeated until the user presses
the ESC key.
Goto:
a) String: Searches each row's displayed fields
for a user-specified string. When
the user hits any key, the next match
is found until no match is found or
the user hits ESC. (F2 key)
b) Rec. Number: Moves the cursor to the user-
specified record number. (F3 key)
c) Rec. Location: Returns EarthBASE to the globe window
at the latitude and longitude
location of the cursor-highlighted
record. (F10 key)
Sort:
a) Rec. Number: Orders the rows by the record number
along the left border. (F4 key)
b) Alphabetize: Orders the rows by alphabetizing
their displayed fields. (F5 key)
c) Rec. Distance: Orders the rows according to which
records are nearest distance to the
globe window's present cursor
location. (F6 key)
Toggle:
a) DFields: Allows the user to choose which fields are
displayed in each row. (F8 key)
b) DQuery: Toggles the displaying of records
according to the following: all records,
all records included by the last query or
all records excluded by the last query.
This function is only available if the
database has not been altered since the
last query. When the database has been
altered, the toggle reverts back to the
'display all records' mode. (F9 key)
FILE CREATION WINDOW 36
EarthBASE
c) DSource: Toggles whether address location data is
constantly read from the disk or read from
its stored location in memory. If the
address location data fields in the opened
XBASE file are not altered by other users
in a network or other processes, there is
no need to read the data constantly from
the disk. Reading the data from the disk
slows the drawing process. EarthBASE is
aware when its own user alters address
location data and updates the data stored
in memory. See the Reference section for
a discussion on networking issues.
(ALT-F1 key)
Print: Prints the displayed rows in the record window
to a delimited file or printer. The last item
on the row, the globe window's display symbol
for that record, will not be printed to the
delimited file. Printing to a file allows the
user to export a delimited database made up of
the fields and records displayed in the record
window. Many databases and utilities (mailing
label utilities, etc.) import delimited files.
The user may specify the delimiting character
which is compatible with the application that
will import the delimited file.
5.3 FUNCTION KEYS
The following hot keys listed below perform tasks in the
record window:

6.0 FIELD WINDOW
This window is entered from the record and globe
windows. The field window, in a spreadsheet format,
contains the field contents of a user-selected record in the
currently opened XBASE file. The user chooses the record
after choosing a menu item in the globe or record window
(edit, copy, create, move). If the field window is
activated by the F5 key in the globe window, the field
window will contain the record closest to the globe window's
cursor location. The record number is displayed on the top
line of the field window. If the globe window is in the
count mode when the field window is entered, the top line
displays whether the record is inside or outside of the
user-specified perimeter. If the globe window is in the
range mode and the range field causes a record's globe
window display symbol to be displayed in red (or larger
font), its record number will be displayed in red (or
reversed color) on the top line of the field window. All of
the function keys described in this section are also found
in the field window menu tree items.
A record's field names are listed in the left column
and the present field values are listed in the right column.
The field value which is currently highlighted by the cursor
is also displayed near the bottom-left border of the window.
The user may edit this value at any time. EarthBASE only
accepts the appropriate characters which are valid for the
specific field type. The F1 key displays a help screen
listing the available function keys.
6.1 FEATURES
The user maneuvers in the window by using the various
keypad keys, in addition to the up and down arrow keys.
Pressing the HOME key returns the cursor to the first field.
Pressing the END key moves the cursor to the last field.
Pressing the INS key moves the cursor to the middle field.
After editing of the fields is completed, the user may save
the record contents in the opened XBASE file by pressing the
F10 key. ALL CHANGES TO THE RECORD WILL BE LOST IF F10 IS
NOT PRESSED BEFORE LEAVING THE WINDOW OR MOVING TO A NEW
RECORD (PAGEUP AND PAGEDN keys). The field window's
contents can be printed to a file or printer by pressing the
ALT-F9 key or the choosing the print menu item. The F7 key
creates a new record without leaving the field window. The
F8 key copies the present field window contents to a new
record without leaving the field window. The F9 key toggles
FIELD WINDOW 39
EarthBASE
whether the field window accesses all records, only records
included by the last query or only records excluded by the
last query.
When the user is ready to exit the field window, he/she
should press the ESC key. Pressing the ESC key does not
save the record contents to the opened XBASE file. Pressing
the PAGEUP and PAGEDN keys load the field window with the
contents of the previous and next record, respectively. The
field window processes all of the non-deleted records in the
opened XBASE file as it performs each of the field window's
file manipulation functions.
The Search & (Edit/F2, Count/F3, Copy/F4, Sum/F5,
Stuff/F6) menu/function key functions search for record's
whose appropriate field (cursor-highlighted field) contains
the user specified-subset string. The F2 key allows the
user to edit each matched record. The F3 key counts matched
records and the F4 key copies matched records to a user-
specified file. The F5 key sums the appropriate field
(cursor-highlighted numeric field) values of matched
records. The F6 key writes the user-specified string to the
appropriate field (cursor-highlighted field) of matched
records.
The QBE & (Edit/ALT-F2, Count/ALT-F3, Copy/ALT-F4,
Sum/ALT-F5, and Stuff/ALT-F6) menu/function keys functions
are query by example (QBE) function keys. They perform the
same function as their search counterpart functions above
except that in order for a record to match, all of its
fields must match all of the field window fields exactly.
Search and QBE matches are not case sensitive (whether
or not a character is capitalized). Spaces are not ignored
in the field window's field nor in a record's field. If the
field window's field contains the '*' wildcard symbol, only
the characters to the left of the '*' symbol are used for
matching. Therefore if a field in the field window contains
an '*' as the first character, all records will be accepted
based on this field.
The special query symbols '<', '>' are also used to
modify the matching constraints for QBE matches. If a
string in a field window field is led by a '<' or '>', a
record's field string will only match if it is less than or
greater than the field window's field string following the
'<' or '>' symbol. It is suggested that the user save
'query' record templates as records in the XBASE file for
commonly executed queries.
FIELD WINDOW 40
EarthBASE
If the count mode is active in the globe window prior
to entering the field window, all record matches must
satisfy the added constraint that the record lie within the
user-specified circular perimeter. This constraint is valid
for all ALT and non-ALT keys.
6.2 MENU ITEMS
A menu lies at the bottom of the data window. Pressing
the / key moves the cursor to the menu bar. The user
traverses the menu by pressing the right and left arrow
keys. The user chooses a menu item by pressing the ENTER
key after it is highlighted.

The window may be exited by pressing the ESC key at the
main menu. Pressing ESC at a lower menu will return the
user to the main menu. Pressing ESC will allow the user to
escape from a menu item once its action is in progress.
Search &: Searches for records whose appropriate field
(cursor-highlighted field) contains the user-
specified string as a subset string. Spaces
are not ignored and the wildcard character '*'
may be used to ignore all characters to the
right and including the '*' character.
a) S & Edit: This search function allows the user to
edit search matched fields. The user
should save the edited record with the F10
key before proceeding to the next matched
record. (F2 key)

matched records. (F6 key)
QBE &: All of the matched record's fields must match
the field window's fields exactly. The query
symbols '<', '>', and '*' affect the query.
Spaces are not ignored. The wildcard character
'*' if used ignores all characters to the right
and including the '*' character.

When the database has been altered or
queried, the toggle reverts back to the
'access all records' mode. This function
allows the user to view records or to
create compound queries based on the last
query.
b) DSource: Toggles whether address location data is
constantly read from the disk or read from
its stored location in memory. If the
address location data fields in the opened

REFERENCE 45
EarthBASE
7.0 REFERENCE
This section lists items in alphabetical order which are
common to all sections of EarthBASE.
DOS SHELL : ALT-D
The DOS operating system may be called without leaving
EarthBASE. EarthBASE is remains resident in memory. Most
of EarthBASE is removed from RAM and stored to disk in the
default directory in a hidden file (up to 600 KB) so that
the system memory can be used by a second program. Once in
the DOS SHELL the user can execute any DOS command. The
user reenters EarthBASE by typing EXIT. When the user types
EXIT at the DOS prompt, EarthBASE is loaded back into RAM
from disk and it continues from the point at which it was
interrupted. This function will not work if there is not
enough room on disk to store EarthBASE's state or if the
file 'command.com' cannot be found in the DOS environment
path. If the computer is turned off while EarthBASE is
saved to disk, EarthBASE's current data and state on disk is
not recoverable. In this case the hidden file will remain
and take up disk space. Use a disk utility to delete the
hidden file. The hidden file name starts with the letter
'D' and is followed by a random number.
DEFAULT DIRECTORY
The default directory is the directory to which files
are saved and from which files are loaded if no pathname is
specified with the file name. This default directory is
shown in the bottom window in most program locations. The
default drive and/or directory may be changed once EarthBASE
has started by using the directory DIR menu item in the
globe window or exiting to the DOS SHELL and changing the
drive and/or directory. The directory pathname may be
specified as part of the file name when loading and saving
files.
DIRECTORY FACILITY
When loading or opening a file, if the file name
contains a wildcard symbol (* or ?) the directory facility
is presented to the user. The available files matching the
wildcard specification are listed alphabetically in the
window. The parent directory and subdirectories are listed
at the end of the file list. The arrow, HOME, END, PAGEUP,
and PAGEDN keys are used to move around in the window.
REFERENCE 46
EarthBASE
Press the ENTER key when the cursor highlights the chosen
file. The directory may be changed by choosing a directory
name at the end of the file list. The window may be exited
without choosing a file by pressing the ESC key.
ERROR MESSAGES
The following input/output error messages are available
during the operation of EarthBASE. The meaning of these
errors may be found in the user's DOS manual.
File not found
Path not found
Invalid format
Not enough memory
File access denied
Invalid file access code
Invalid drive number
Disk write error
Disk read error
File not assigned
Invalid numeric format
Disk is write protected
Drive not ready
Unknown command
Bad pathname length
Disk seek error
Printer out of paper
Device write fault
Device read fault
Hardware fault
Disk write error
Disk read error
File not assigned
EarthBASE also notifies the user when there is too
little RAM memory to accomplish a certain task. EarthBASE
notifies the user if the appropriate *.BGI (graphics driver)
and other necessary files are not in the default drive or in
the DOS environment path when it attempts to start.
EarthBASE also notifies the user of any file errors as it
attempts to output data. If the printer is turned off when
EarthBASE attempts to print output, EarthBASE will wait
without displaying an error message until the printer is
turned on. If the printer is turned off while printer or if
it runs out of paper, an error message will be displayed.
REFERENCE 47
EarthBASE
LINE EDITOR
When EarthBASE is in editing mode, the following
editing keys apply:
SPACEBAR: Creates a space at the cursor position.
BACKSPACE: Deletes a character to the left of the
cursor.
DEL: Deletes a character to the right of the
cursor.
HOME: Moves the cursor to the beginning of the
string.
END: Moves the cursor to the end of the string.
INS: Toggles the editing mode between 'insert'
and 'non-insert'. In the insert mode,
when a key is pressed, the keystroke is
entered at the cursor position and all
characters beginning at the cursor
position and to the right are moved one
position to the right. In the non-insert
mode, the existing character at the cursor
position is overwritten by the keystroke.
In the insert mode the cursor is thin and
in the non-insert mode the cursor is fat.
The insert status is highlighted in the
bottom portion of the screen whenever
EarthBASE is in the editing mode.
ENTER: Accepts the entry and moves the cursor to
the next item.
MOUSE
Inputs are accepted from a Microsoft compatible mouse
if the appropriate driver is installed. Pressing the left
mouse button represents pressing the ENTER key. Pressing
the right button represents pressing the / key. The ALT-F4
key in the globe window adjusts mouse and track ball
movement sensitivity. A larger number entered at the ALT-F4
prompt causes less sensitivity to input device movement.
REFERENCE 48
EarthBASE
NETWORK LAN CAPABILITIES
EarthBASE is compatible with DOS compatible networks.
EarthBASE's record locking feature is active if DOS Version
3.0 or greater is present in the workstation. XBASE
database files may be shared my multiple users. Writing to
a file's record locks that individual record to prevent
simultaneous writes to it. Writes do not block reads and
reads do not block reads or writes. If multiple users are
to share the EBASE.EXE file, its attribute should be set to
read status using the following command:
attrib +r EBASE.EXE
If EBASE.EXE is shared by multiple users, multiple licenses
must be purchased for the maximum number of simultaneous
users.
EarthBASE stores query, range and sorting history data
in each user's computer memory. This history data is not
updated when another user alters the shared database. This
history data is only accurate then, at the instant it is
created.
Address location data (where to locate a record on
globe) is stored in memory when the database is opened by
each user and when a record is created during a session.
The ALT-F1 key in the globe, field, and record windows
toggle whether EarthBASE uses the address location data
stored in memory or always reads current address location
data from the disk. Reading address location data from the
disk slows the drawing process. If other users or processes
are altering address location data often, the user should
cause EarthBASE to constantly read the data from the disk or
read the data from the disk on a periodic (user must toggle
ALT-F1 key at his/her discretion) basis.
Each instance of EarthBASE, on a regular basis, checks
the database for records created or deleted by other users.
Each instance of EarthBASE is aware when its own user alters
address fields and appropriately alters the address location
data in memory.
