A NOTE ABOUT YOUR EVALUATION COPY
PC-CALC now includes a 110-page typeset User Guide. The manual
has become far too large to include on diskette. Portions of
the manual are included here, so you can evaluate the software.
At several places in this copy of the User Guide you'll see the
following notice.
*****************************************
* Section omitted. Evaluation copy. *
*****************************************
We honestly feel that we've supplied enough of the manual to
allow you to make a good evaluation of the program. There are
several reasons why we didn't provide the entire manual on disk.
- We want to continually remind you to pay for PC-Calc if
you're using it. We've priced it so that you can afford
it. Frankly, it's the best bargain in the industry. We also
suspect and hope that you (the buying public) will want to
cast your "vote" for lower priced software by paying readily
for such programs. Other software publishers would then be
forced to take notice.
- We feel that the honesty of our "registered" users should be
rewarded. They're entitled to some extra value that should
rightfully be denied to those who don't pay.
- It takes up too much room on the diskette.
We trust that you'll be open-minded about the omissions. We hope
that we can soon add you to our list of very satisfied customers.
PC-CALC(tm) USER GUIDE Page 4
INTRODUCTION
PC-CALC is an easy-to-use "Visible Spreadsheet" program. If you
work with numbers, at home, on the job or at school, PC-CALC is
for you. Whether the task is simple or complex, PC-CALC can help
you. By using its powerful commands, reports can be produced in
minutes that would take hours to do manually, or days to write in
BASIC.
Here are some examples of how people are using PC-CALC:
- Computing interest and principal on loans, mortgages,
savings accounts.
- Preparing payroll journals, sales journals, accounts
receivable journals.
- Doing income tax computations, computing depreciation,
accumulating income and expenses.
- Preparing business forecasts, P&L's, ten-year projections,
etc. and then playing "what if..." to see the impact of
changing one or more numbers.
- Analyzing investments, balancing checkbooks, keeping budgets.
- Preparing homework assignments for classes in bookkeeping,
accounting, math, etc.
Spreadsheets created with PC-CALC can be displayed and altered on
the screen, printed out, saved on disk and reloaded for further
changes or review. If you create a really wide spreadsheet that
won't fit on one page, no problem. PC-CALC will print two pages
that can be attached to make one wide spreadsheet.
And spreadsheets are not limited to the size of your computer
screen. PC-CALC will scroll up, down and sideways to give you a
spreadsheet up to 26 columns wide and 255 lines long. Numbers and
words can be placed anywhere on the spreadsheet. The width of
each column of your spreadsheet can be any size from 1 character
to 75 characters wide, or it can be "zero" characters wide, which
means it exists and contains data, but is hidden from view. A
number can have from one to nine decimals, or no decimals at all.
Spreadsheets can link to other spreadsheets to extract data,
providing a "3-dimensional" capability. And if you are a PC-FILE
database user, PC-CALC can reach into your databases and extract
data or add up numbers. And there is no limit to the number of
PC-CALC(tm) USER GUIDE Page 5
databases that can be accessed by a single spreadsheet. These are
just a few of the features that PC-CALC provides.
This manual describes all the features of PC-CALC in detail. It
is recommended that the manual be read completely before using
PC-CALC, but you will find that it is so easy to use, many of its
features can be mastered even without the documentation. For that
reason, this manual has been organized as a reference document
rather than a tutorial. There is a tutorial section at the
beginning, titled "A Brief Tutorial", but the rest of the manual
is designed for quickly finding information about specific
commands and functions.
----------------------------------------------------------------
SYSTEM REQUIREMENTS
PC-CALC runs on the IBM PC and PCjr or compatible systems with
this minimum configuration:
- 128K computer memory.
- An MSDOS or PCDOS operating system version 1.1 or later.
- A monochrome or color monitor with either 40 or
80 column display. A color graphics board is not
necessary, but if you have one, PC-CALC will
format its screens in your choice of colors. If
your computer has less than 25 lines, PC-CALC can
be configured for a shorter screen (8 lines
minimum).
- A double sided diskette drive. PC-CALC is also
compatible with hard disks and electronic disks.
- A printer is optional. PC-CALC will run on most
printers. Special formatting options are
available for the Epson printer and compatibles.
PC-CALC(tm) USER GUIDE Page 6
GETTING STARTED
1. Turn on your computer and load the MS-DOS operating system.
(The PC-CALC diskette does not have MS-DOS on it, so use any
diskette that does.)
2. Put the PC-CALC diskette in drive A. (If you only have one
copy of the PC-CALC diskette, this is a good time to make a
backup copy of it.)
3. At this point, most users will simply type:
PC-CALC
and press ENTER, which will load and run the program. However,
there are some special cases when PC-CALC cannot automatically
configure itself, and an extra code must be entered, as
indicated below:
Computers with a forty-column display:
PC-CALC 40
Computers with a color board, but a monochrome monitor:
PC-CALC BW
Computers with a color board, but a monochrome monitor, and a
forty-column display:
PC-CALC BW40
Non-IBM computers which do not have IBM-compatible video
memory mapping (such as the Tandy 2000):
PC-CALC SL
4. Press any key to move from the PC-CALC banner screen to the
spreadsheet screen.
5. Check the screen. If it doesn't look right, or if it doesn't
show "A1 >" in the lower left corner, read the Configure (/C)
section before proceeding. Otherwise, PC-CALC is ready to use!
PC-CALC(tm) USER GUIDE Page 7
A BRIEF TUTORIAL
Now that you have PC-CALC loaded in your computer, note that
across the top of the screen are letters: A, B, C, etc. These
letters identify the columns of the spreadsheet. Down the left
side are numbers. These numbers identify each row of the
spreadsheet. Each coordinate in this grid is called a "cell". For
example, the cell where the cursor is currently located is called
"A1"; to its right is "B1"; below it is "A2"; at the end of the
spreadsheet (not currently on the screen) is "Z255".
Press the arrow keys and you will find that you can move the
large cursor (called the "cell cursor") around on the screen.
When moving left and right, it moves one column at a time. Up and
down it moves one row at a time. In the lower left corner of the
screen is an indicator called the "cursor coordinate", which
shows the cell currently occupied. As the cursor is moved about
the screen, this cursor coordinate will rapidly change to the new
cell address.
Press the right-arrow several times and you will see the screen
"scroll sideways". In other words, column A will disappear on the
left, and all the other columns will shift to the left, making
room for a new column on the right. If you keep pressing the
right-arrow key, eventually you will come to column Z and the
cursor will no longer move. You have reached the edge of the
spreadsheet. Using the down arrow key you can make the screen
"scroll up" until the last row of the screen, row 255, is
displayed.
When pressing the arrow keys to scroll, if you hold down the
arrow key, causing it to rapidly repeat, you will notice
something a bit different. The cursor coordinate in the lower
left corner of the screen starts advancing rapidly, but the
screen is not redisplayed until you let up on the arrow key. This
allows you to scroll quickly to any position in the spreadsheet
without waiting for the screen to be refreshed.
Now let's try putting some data on the spreadsheet. Move the
cursor to coordinate B4, and type 12345 then press the ENTER
key. As you type the number, you will notice that it is displayed
on the bottom line of the screen. This line is called the "entry
line". When you press ENTER, the number on the entry line
disappears, and is redisplayed up in the spreadsheet at
coordinate B4. But it is slightly different. Instead of being
simply the 12345 you typed, it is 12,345.00 and it is shifted to
the right of the column. The number is displayed this way because
of certain "defaults" in PC-CALC for displaying numbers. Unless
PC-CALC(tm) USER GUIDE Page 8
otherwise specified, all numbers will have two decimal places,
will have commas between the thousands, and will be "right-
justified" in the column. Of course it is possible to change
these defaults, for specific cells or for the whole screen, and
this will be discussed later in the "Format Command" section.
Now press the up-arrow and move the cell cursor to B2. Type the
following (including the quote mark):
"This is a test of PC-CALC.
and press the ENTER key. As you are typing, if you make an
error, you can use the arrow keys to move the cursor back and
forth across the entry line, then make typing corrections. After
pressing ENTER, look at cell B2. It will now contain the text
you typed, and the text will overlap into cells C2 and D2. Text
is allowed to overlap cells in PC-CALC, provided the cells to the
right have nothing in them. (Note: If your text didn't appear in
cell B2, make sure you typed the quotation mark as the first
character; the " mark tells PC-CALC that the data is text.)
Now move the cursor to B6 and type:
B4+B4
then press the ENTER key. Cell B6 should display the number
24,690.00 which is the sum of 12345 plus 12345. Let's examine
what happened. By moving the cursor to B6, you told PC-CALC to
put the result of the formula into B6. The formula B4+B4 told
PC-CALC to get the number at B4, add it to itself, and put the
result in B6. The formula could have been simpler or more complex
and PC-CALC would have immediately gathered up all the numbers
needed, computed the new value, and displayed the result at B6.
Looking at the screen, you have now entered all three types of
data that can go on a PC-CALC spreadsheet:
At B2 you entered the "text" - "This is a test of PC-CALC.
At B4 you entered the "value" - 12345
At B6 you entered the "formula" - B4+B4
Any cell on the spreadsheet can contain text, a value or a
formula. Now move the cell cursor to each of the three cells with
data in them. As the cell cursor moves into a cell, notice that
the "cell contents" are displayed at the bottom of the screen on
the "message line". The cell contents are the actual letters or
numbers you typed when entering data into the cell.
Now as a final exercise in this brief tutorial, type /Z Y to
clear the worksheet (a complete explanation of the Zap (/Z)
PC-CALC(tm) USER GUIDE Page 9
command appears later in the manual). Move the cursor to each
cell listed below, and enter the data exactly as shown. If you
get an error message on any of the lines, press CONTROL-C (hold
down CONTROL while pressing C) to clear the entry line, then type
it again. All lines should go in as shown without errors.
At Coordinate: Enter this data:
B2 "Compute Annual Interest
B4 "Rate:
C4 5.5
B6 "Year
C6 " Balance
D6 " Interest
B7 "1983
C7 5000
D7 C7*C4/100
B8 "1984
C8 C7+D7
D8 C8*C4/100
B9 "1985
C9 C8+D8
D9 C9*C4/100
B11 "Totals
C11 C9+D9
D11 SUM(D7:D9)
When the preceding data has been entered, your spreadsheet screen
should look like this:
A B C D
1
2 Compute Annual Interest
3
4 Rate: 5.50
5
6 Year Balance Interest
7 1983 5,000.00 275.00
8 1984 5,275.00 290.13
9 1985 5,565.13 306.08
10
11 Totals 5,871.21 871.21
This simple spreadsheet computes the interest on a savings
account at a specified annual interest rate. Since this is a
sample exercise, the spreadsheet has been kept small, but later
you will learn how to use the "Replicate" command to extend a
spreadsheet like this one to fifty years or more, in a matter of
seconds. The "SUM" function in cell D11 is simply adding up the
numbers in D7 through D9, so you can see the accumulated interest
for all three years.
PC-CALC(tm) USER GUIDE Page 10
Now let's try some "what if" experiments. What if the interest
rate were seven percent instead of 5.5? To see the result, simply
move to cell C4, type 7 and press ENTER. All the figures on the
screen are immediately updated with the new interest computation.
Or what if the interest were 18%? Try it. What if there were only
$850.25 instead of $5000? Move the cursor to C7 and enter 850.25
and the spreadsheet will immediately be recalculated.
A printed report of the spreadsheet is often desirable. Ready
your printer, then type the command /P which invokes the Print
routine. You will then be prompted for several options. For this
simple spreadsheet, just press ENTER for each of the options.
The spreadsheet will print, and PC-CALC will return to its
original state, waiting for another command.
Finally, before exiting from PC-CALC, let's save the spreadsheet
on disk. Type /S to invoke the Save routine. You will be asked to
enter the name of the spreadsheet; type TEST and press ENTER.
PC-CALC will say "Saving file. Stand by . . ." and the file will
be written to your PC-CALC disk. It can later be loaded using the
/L command. (Note: If you get a message saying "File Exists.
Overwrite Y/N?", it only means that someone before you saved a
file called TEST. Reply Y to the message, and your TEST file will
overwrite the one already on the disk.)
This concludes the brief tutorial. The remainder of this manual
is organized for reference. It is a good idea to read through it
to familiarize yourself with some of the more sophisticated
commands. But the best way to learn PC-CALC is to use it.
PC-CALC(tm) USER GUIDE Page 11
GENERAL INFORMATION ABOUT PC-CALC
The maximum size of a PC-CALC spreadsheet is 26 columns by 255
rows. The maximum content of a cell is 64 characters, and the
maximum column width is 75 characters. The amount of memory
available for your spreadsheet is displayed at all times in the
lower left corner of the screen. It is a number followed by the
letter "K". If it says 16K, for example, you still have 16K of
memory available for typing text and formulas. If it says 1K, be
careful. Your spreadsheet is getting too big and may fill memory,
causing the "MEMORY FULL" message.
Three types of data may be entered into a cell:
TEXT: Precede a text entry with a quotation mark or
apostrophe. Any character may be typed in a text
entry, and all of the data will appear in the cell.
If the text data is wider than the column, and there
is nothing in the cell to its right, it will overlap
into subsequent cells. If there is something in the
cell to its right, the text data will be truncated on
the display and printout. The entire text entry is
retained in the cell, even if it does not all
display. Text may be left- or right-justified in the
column by using the Format (/F) command. Text entries
can be from 1 to 64 characters in length.
VALUE: A value is a number. When a value is entered into a
cell, it is displayed according to current defaults.
For example, you enter 12345 and it is displayed as
12,345.00. Each value is displayed according to the
display attributes of the cell. These attributes can
be changed by using the Format (/F) command. In
PC-CALC a value cannot exceed 12 digits in total
length, and it can have no more than 9 digits to the
right of the decimal place. While these restrictions
in number size are acceptable for personal and
business applications, they may preclude the use of
PC-CALC for some scientific applications.
FORMULA: A formula is one or more cell coordinates and/or one
or more values, combined using arithmetic operators.
For example, a formula might simply add together a
string of numbers: A1+B1+C1+D1 or it might perform a
more complex task: A1*2.5+(SUM(A1:D1)-.00005).
Formulas can be up to 64 characters in length.
A formula can have any combination of cell coordinates, values,
math functions, statistical functions and IF functions, each
separated by an operator (+, -, *, /, ^). No blanks may be
PC-CALC(tm) USER GUIDE Page 12
entered; if the space bar is pressed, PC-CALC ignores it.
Exponentiation (^) is done first, then multiplication (*) and
division (/) are done, and finally addition (+) and subtraction
(-) are done.
Parts of a formula may be nested in parentheses, up to thirty
levels. These rules apply to formulas with parentheses:
- Every left parenthesis must have a matching right
parenthesis, or else the "Mismatched parentheses" error
will occur.
- Parenthesised expressions are always evaluated from the
inner-most to the outer-most. Using parentheses, the
precedence of the arithmetic operators can be overridden.
For example, A1+5*C1 will do the multiplication first,
then the addition. (A1+5)*C1 will do the addition first.
- Use parentheses to separate two operators in a row. For
example, to multiply A1 times -5, the formula A1*-5 is not
valid because the * and - are together. Instead use this
format: A1*(-5) to accomplish the arithmetic.
A formula may also include a function, or consist solely of a
function. Examples:
A1+SUM(B1:E1)
TAN(A1)
For specific information on each function, see the alphabetical
reference section.
PC-CALC(tm) USER GUIDE Page 13
KEYBOARD CONVENTIONS
Certain keys perform special functions in PC-CALC. These keys
fall into two general categories; cell cursor keys and entry line
keys. Once you have started entering data, PC-CALC goes into data
entry mode, and only entry line keys will be recognized from the
keyboard until the entry line is entered or canceled. In some
cases, the same key that is used for cell cursor movement
performs a different function when you are entering data. For
ease of reference, the keys are listed within category.
CELL CURSOR KEYS
Special Key Alternate Purpose of key
----------- --------- --------------
UP ARROW CONTROL-E Moves cell cursor up one row.
DOWN ARROW CONTROL-X Moves cell cursor down one row.
LEFT ARROW or CONTROL-S Moves cell cursor left one column.
BACKSPACE or

UP/LEFT ARROW CONTROL-W Moves the screen down one row
without moving the cell cursor.
DOWN/LEFT ARROW CONTROL-Z Moves the screen up one row
without moving the cell cursor.
CONTROL-N Inserts a row above the row where
the cell cursor is located.
CONTROL-Y Deletes the row where the cell
cursor is located.
= CONTROL-Q Prompts for a cell, and jumps to
that cell.
PC-CALC(tm) USER GUIDE Page 14
ENTRY LINE KEYS
Special Key Alternate Purpose of key
----------- --------- --------------

the formulas in the spreadsheet
are re-computed.
/ Prompts for a command code.
Note that some computers will not have all the keys described
here. For the important keys, an alternate CONTROL-key has been
assigned, which conforms to the CONTROL-key assignments of many
popular software packages. Further discussion of each key
follows:

-----------------------------------------------------------------
FORMAT Command (/F)
Purpose: Sets the formatting options for a cell, a range of cells
or the entire spreadsheet.
Prompts: Enter /F and you will be prompted:
"Enter range to be formatted (or ALL)."
You can enter a single cell, a range of cells (which may
be a block), or ALL. To format only the current cell,
press ENTER or comma. The next prompt is:
"Decimals, Width, Justify, Commas, *, $, (, %."
Enter a D, W, J, C, *, $, ( or % to indicate which type
PC-CALC(tm) USER GUIDE Page 19
of formatting you want to do. The next prompt depends on
which option you select:
D - "Number of decimal places (0 to 9)."
The number of places to the right of the decimal
can be changed using this command. This number
of decimals is used on the screen display, on
the printed output, and in computations.
W - "Enter column width (0 to 75)."
The width of a column or range of columns can be
changed using this command. A column width of
zero causes the column to be "hidden", allowing
data to be stored without being seen.
J - "Right-, Left- or Center-justify."
Specify "L" to have numbers shifted to the left
side of the column. Specify "R" to have text
shifted to the right side of the column. "C"
will center the cell's contents. PC-CALC
defaults to right-justify for numbers and left-
justify for text unless overridden by this
command.
C - "Commas between thousands (Y or N)."
To have 12345.00 print as 12,345.00 specify "Y"
to this prompt. To remove the commas from a
number, specify "N". For example, if the number
is a year such as 1985 you would not want it to
print as 1,985.
* - "Print numbers in bar graph format (Y or N)."
If a cell contains a value or formula, the
result will be displayed as a string of
asterisks. Using this format option, you can
produce simple horizontal bar graphs.
$ - "Print leading dollar sign (Y or N)."
If you specify Y, a dollar sign will be printed
immediately to the left of the most significant
digit.
( - "Negative numbers in parentheses (Y or N)."
If Y is specified, a negative number will have
parentheses around it, rather than a minus sign.
To switch back to minus sign, specify N. Note:
When this format option is specified, positive
numbers have one blank space to the right. This
is necessary so a column of positive and
negative numbers will line up properly.
% - "Print a percent sign to the right (Y or N)."
If Y is specified, a percent sign will be
printed on the right of the number. Note: this
PC-CALC(tm) USER GUIDE Page 20
parameter has no bearing on the computation of a
formula; it is strictly a formatting option.
Each of the formatting options above which have
responses of "Y" or "N" will also accept a response of
ENTER. If you press the ENTER key instead of Y or N, the
formatting options for the specified cell(s) will clear
the format option, so the cell's format will revert to
the default (global) setting.
After responding to one of the formatting options,
PC-CALC will repeat the prior prompt, allowing you to
specify more than one formatting option for a cell or
range.

PRINT Command (/P)
Purpose: Prints a hard copy report of a spreadsheet.
Prompts: Enter /P and you will be prompted:
"Enter range to be printed (or ENTER for all)."
The word ALL will appear on the entry line. If you want
to print only part of the spreadsheet, enter the
coordinates as a range (for example: A1:G15) over the
word ALL, then press ENTER or comma. To print the
complete spreadsheet, press ENTER. The next prompt is:
"Enter page width (number of characters across
printout)."
The number 80 will appear on the entry line. If the
printer is set up to accomodate an eighty-character
printout, just press ENTER. Otherwise, enter the width
of the printer page. The next prompt is:
"Enter page length (number of lines per page)."
The number 60 will appear on the entry line. If you are
printing on normal eleven-inch paper, at six lines per
inch, press ENTER. Otherwise, figure out how many lines
will print on a page and enter it. The next prompt is:
"Options: D=dbl space, S=setup, P=pause,
C=contents, B=border, O=offset"
If no special options are desired, just press ENTER.
Otherwise, enter one or more option characters and press
ENTER. The options are:
D - Double space the printout. Puts an extra blank line
between each line of your spreadsheet.
S - Allows you to send special setup codes to the
printer, to change character size, etc. If S is
selected, another prompt will follow, allowing the
setup codes to be entered.
P - If the report is more than one page, PC-CALC will
pause after each page. This option is useful when
using a printer that takes single sheets of paper.
C - Prints the contents of each cell rather than the
display. Each non-blank cell is displayed, one per
line, with its coordinate, attributes and contents.
B - Causes the row and column borders to be displayed on
PC-CALC(tm) USER GUIDE Page 25
the printed spreadsheet.
O - Specifies a left margin width on the report. If not
specified, the default is seven. If "O" is entered,
you are prompted for a new offset (see below).
SETUP
If "S" was specified above, the following prompt will be
given next:
"Enter printer setup codes, then ENTER."
For some printers, the setup codes have been built into
PC-CALC's /Configure routines. The standard diskette
comes configured for Epson (IBM) printers. The setup
prompt will have a second line saying:
Epson printers: "A" = 10 cpi,
"B" = 12 cpi, "C" = 17 cpi.
If your PC-CALC has been configured for another printer,
that printer's name will appear instead of Epson. If the
named printer matches your printer, you can alternately
enter the letters A, B or C to set your printer spacing
to 10, 12 or 17 characters per inch, respectively.
If PC-CALC has not been configured for your printer, you
can still send setup codes to the printer. Just
Press any key (other than A, B or C) at this time, and
its ASCII value will be sent directly to the printer.
For example, if the sequence "ESC,M" sets your printer
to twelve characters per inch, press the Escape key,
then the capital M. When all the setup codes have been
entered, press ENTER.
Some printer setup codes are special ASCII characters.
If you need to send an ASCII 15 to your printer, for
example, there are two ways to do this:
1. Hold down CTRL and press O (the letter). CTRL-O
at the keyboard generates an ASCII 15. (O is
the 15th letter of the alphabet. CTRL-A
generates an ASCII 1, etc.)
2. Hold down the ALT key, and type the number you
want sent on the numeric keypad. For example,
to send an ASCII 15, hold down ALT, press the
one then the five key, and let go of ALT. An
ASCII 15 will be sent. This feature is built
into the hardware of the IBM PC, and may not be
available on all compatibles. Be sure to type
the number on the numeric keypad, and not on
the numeric row across the top of the keyboard.
PC-CALC(tm) USER GUIDE Page 26
OFFSET
If "O" (offset) was specified as one of the options
above, PC-CALC will now prompt:
"Enter the page offset (left-margin size)."
The entry line will contain a "7". Enter any number,
from 0 to 99, and that many blanks will be printed to
the left of the spreadsheet.
The last prompt from the Print command is:
"Printer or Disk."
Specify P to send the output directly to the printer. If
D is specified, you are prompted:
"Enter the file name."
Enter a valid MSDOS file name, and the printed output
will be written to a file by that name. You can print it
later with the MSDOS "COPY filename PRN:" command, or
access it with your word processor for further editing.

REPLICATE Command (/R)
Purpose: Copies data from a cell or range to another cell, range
or block, and optionally adjusts the cell coordinates in
formulas. The format attributes such as decimals,
commas, etc. are copied along with the data. This
powerful command allows cells to be copied over and
over, with formulas adjusted, saving considerable data
entry.
Prompts: Enter /R and you will be prompted:
"Enter the "from" range."
Enter a single cell or a range of cells (example:
A1:G1). If the "from" cell is the current cell (where
the cell cursor is currently), just press ENTER. The
current cell will be used. The next prompt is:
"Enter the "to" range."
Once again, enter a single cell or a range of cells.
This range specifies the receiving field. If the "to"
cell is the current cell, just press ENTER.
If your ranges are valid, the data in the "from" range
will now be copied to the "to" range. During the copying
operation if a formula is encountered in the "from"
range, a message will be given for each of the variables
in the formula. For example:
"(A5) Adjust A3 Y or N?"
This sample message says that in the "from" cell A5 it
found a formula. That formula contained a reference to
A3. If you reply Y to this message, each replication of
A5 will be changed so the formula refers to A4, then A5,
then A6, etc. If you reply N to this message, all
replications will refer to A3, unchanged. See the
examples below for more information.

At this point, you have two choices: display a disk
directory or save the spreadsheet file. If you press
ENTER, the directory of the currently logged disk drive
is displayed. By entering A:, B:, etc. you can display
disk directories on other drives.
If instead you enter a file name, PC-CALC will save the
currently displayed spreadsheet onto disk, giving it
that name. The file name can be any valid MSDOS file
name; i.e. eight characters or less, optional extension,
optional drive designation. Some examples of valid file
names are:
LOAN1
B:WORKSHT5.OLD

IF YOU NEED HELP
It's our express goal to provide the highest quality programs for
the lowest price in the industry. Nobody benefits more from this
policy than you, the computer user.
Our products are so overwhelmingly popular that the telephone
here rings almost constantly. While the author heartily enjoys
talking with users, it's becoming impossible to spend any time
enhancing the programs.
If we have to install support lines and hire technical personnel
to provide telephone assistance, the price of our products will
have to be increased. We don't want to do this, and we're certain
that you agree.
We beg your indulgence with this problem. Please don't call
unless it's an "emergency". Before calling, carefully read the
User Guide one more time, looking for an answer to your question.
The best way to receive help with your questions, or a response
to your suggestions, is to write us a letter. Be sure to
carefully detail the problem and all symptoms. Please include a
stamped, self addressed return envelope. We'll try to respond to
all such mailings.
One last word. If you're not a registered user, please don't call
or write. Because our availability is a limited resource, we feel
it's only fair that we spend it on our registered users.
