Information about “BOOK MEMO DISPLAY”
BOOK MEMO DISPLAY takes any ASCII text file and turns it into a computer
book. Access any chapter, and any page in that chapter from the
computer index. No more scrolling through long documents to find the
section you want.
You provide the text file, this program converts it into a new file that
is divided by chapters and pages. It also creates an index display that
lists these chapters. When the index is displayed you can directly
access any chapter with a single keystroke. You can display successive
pages within a chapter with another keystroke. Move forward or backward
through the pages, or go back to the index to change chapters.
To make your own "book" you will need a wordprocessor that makes
ASCII files (most do).

DISPLAY.DOC
DISPLAY DOCUMENTATION
This is a system for generating and displaying dynamic
messages.
This set contains three programs named, MAKDISP1.COM,
MAKDISP2.COM and DISPLAY.COM, with several short supporting
and/or sample files. They will assists the non-programming user
in the preparation and presentation of dynamic ASCII displays.
These displays consist of up to 99 sequential panels consisting
of five rows of twenty five characters. You can use any of the
standard characters in either upper or lower case through the
normal keyboard. You can also use any character from the extended
ASCII set up to [255] by holding down the ALT key and entering
the number of the desired character through the keypad on the
right of the keyboard, then releasing the ALT key.
The programs also permit you to select from a limited number
of foreground and background attributes, including blinking
foreground. You can also specify the display time in seconds for
each panel of the display. As an added convenience to the viewer
of the display, the timer subroutine has a built in feature that
causes the display to advance to the next panel whenever the
viewer presses any key without regard to the remaining time.
To create a display with the program, copy MAKDISP1.COM,
MAKDISP2.COM and DISPLAY.COM into any root, directory, or
subdirectory. This directory should not contain a file named
DISPLAY.FIL or any file named DISP.Nxx where the x
represents any decimal digit. Then enter that directory (if you
are not already in it) and type MAKDISP1 followed by pressing
the ENTER key. MAKDISP1 will clear the screen and display a
brief message and a highlighted, bordered, rectangle near the
center of the screen.
The normal cursor will be in the upper left corner of this
rectangle waiting for your first character. Type in anything you
want displayed in this panel, (including the extended ASCII
characters using the ALT key). DO NOT PRESS ENTER AT THE END OF
THE LINE. At the end of the line the cursor will automatically
advance one line and move to the left of the rectangle. On the
last line it will not advance but it will perform an automatic
wrap-around and write over on this last line.
MAKDISP1.COM also supports the up arrow, down arrow, left
arrow, and right arrow keys as long as they do not leave the
highlighted box. It also supports a modified form of backspace,
moving the cursor back one space and overwriting that position
with a blank space. It even includes necessary line and position
modification at the left boarder, but it will not exit the
highlighted area.
When you are satisfied with the composition of this panel,
press the ENTER key and MAKDISP1.COM will put the panel into a
small file named DISP.Nxx where xx is the panel number. It will
then tell you which panel number you have just completed and ask
you if you want another panel. If you press Y it will repeat
the process for the next panel and if you press N it will
return you to the DOS prompt. MAKDISP1.COM will also exit
with a polite message and return you to DOS if it finds a file
named DISP.Nxx because it will assume that it is from a
previous run and that you do not want to overwrite it.
Your next step is to type MAKDISP2 and press the ENTER
key. MAKDISP2.COM begins by creating the file named DISPLAY.FIL
and entering a four digit password beginning with the second
byte. This is to prevent DISPLAY.COM from putting garbage on
the screen if you accidentally follow DISPLAY with the name of
a real existing file that you did not intend to display. With
this feature a large commercial user could issue individualized
display systems that could peacefully coexist in the same
environment. The first byte is a counter telling how many panels
are combined in this file.
After the password, MAKDISP2.COM, in a numerical sequence,
puts the contents of each DISP.Nxx file, with an appropriate
header block, into the file named DISPLAY.FIL. The header block
in the Shareware version of this system consists of two bytes.
The first byte is the number of seconds for this panel to be
displayed. The second byte defines the attributes for the
display including foreground, background, intensity and blinking.
In the commercial version this header can be six bytes long,
with one byte defining the horizontal panel size, a second byte
defining the vertical panel size, and two bytes defining the
screen location of the upper left corner of the panel. Colors
also increase the number of options in the menu for the attribute
byte.
MAKDISP2.COM asks you how many seconds you want to display
this panel and you enter one or two digits from the keyboard as
your answer. If your first digit is not 0 and you want a display
time of less than ten seconds you can press ENTER and the program
will accept the single digit. If you press a second digit, you
don't need to press ENTER . The program goes on without it. The
program ignores other keys.
The program asks you to choose a color attribute by pressing
a key from a menu of possibilities. It ignores all other keys
except ENTER. If you press ENTER, the program assumes an
attribute of normal white foreground on a black background.
Similarly, in response to the blink attribute question, if you
press ENTER the program assumes that you don't want the display
to blink. It ignores all other keys except Y or N (either
uppercase or lowercase).
When MAKDISP2.COM has processed all of the sequentially
numbered DISP.Nxx files it will close DISPLAY.FIL and return
you to the DOS prompt. To review it type DISPLAY DISPLAY.FIL
and press ENTER .
If you are satisfied with the result rename DISPLAY.FIL to
something appropriate like BOB, JUDY, LOVE, XMAS, BIRTHDAY,
or any other FILENAME (with or without an extension). Then, if
you want it to be really easy, make a one line .BAT file with
the COPY CON command that says DISPLAY FILENAME ^Z .
For example if you have created a display for Christmas and
used the REN DISPLAY.FIL XMAS.D25 <ENTER> command to rename
DISPLAY.FIL to XMAS.D25 then you can make XMAS.BAT like this:
COPY CON XMAS.BAT <ENTER> DISPLAY XMAS.D25 ^Z <ENTER> .
(NOTE: the ^Z is the END-OF-FILE character and you can make
it by holding down the CTRL key and pressing Z or by pressing
F6 )
Now you can put DISPLAY.COM, XMAS.D25, and XMAS.BAT on
a formatted disk and send it to a friend with the instructions to
put the disk in drive A: and, assuming the computer has already
been booted up, type A:\XMAS <ENTER> . Your friend will see your
personally prepared dynamic Christmas greeting!

Disk No: 1807
Disk Title: Book Memo Display
PC-SIG Version: S1
Program Title: Book Memo Display
Author Version: 1.0
Author Registration: $7.00
Special Requirements: None.
BOOK MEMO DISPLAY takes any ASCII text file and turns it into a computer
book. Access any chapter, and any page in that chapter from the
computer index. No more scrolling through long documents to find the
section you want.
You provide the text file, this program converts it into a new file that
is divided by chapters and pages. It also creates an index display that
lists these chapters. When the index is displayed you can directly
access any chapter with a single keystroke. You can display successive
pages within a chapter with another keystroke. Move forward or backward
through the pages, or go back to the index to change chapters.
To make your own ``book'' you will need a word processor that makes
ASCII files (most do) and MAKEBOOK.COM (part of this program) to combine
the individual page files and insert the control characters.
