PUSH.COM and POP.COM Documentation
PUSH and POP were written by Larry Lockwood of the Orange County IBM
PC Users Group. They are short assembler programs availabe from the IBM EBBS.
PUSH is a memory-resident program which allows the user to press the
Shift-PrtSc keys and instead of printing the screen to the printer, the
screen is printed in a file with colors, etc. You must reboot to use the
Shift-PrtSc to copy the screen to the printer. The syntax for loading is:
A>PUSH drive:filename (do not use extensions)
(I use my ramdisk, it will make access faster later.)
Whenever you then press the Shift-PrtSc key that screen is saved in a file
named filename.XXX. XXX is the extension which PUSH generates. The first
screen is filename.001, the second is filename.002, etc. (It is so fast, the
cursor does NOT move like it usually does on a Shift-PrtSc. Each text screen-
image file is 4100 bytes. Each graphics screen file is 16,300 bytes giving
you approximately 88 text or 22 graphics screens on a diskette. You can then
rename the files yourselves for more meaningful names.
POP then retrieves the file:
A series of POP's in a batch file could give you a very nice presentation. And
that isn't all. POP also allows you to change colors and blinking
characteristics, allows you to then resave the screen or if you make an error,
recall the original screen. The function keys do the following:
F1 - Changes background colors or graphics images and border colors
of text images.
F2 - Toggles graphics colors back and forth between palettes 0 and 1.
F3 - Selects background colors for individual characters in text mode.
F4 - Selects foreground colors for individual characters in text mode.
F5 - Exercises left forefinger (Lockwood's Joke).
Shift/F7 - Reloads original file.
Shift/F8 - Saves modified image. It destroys the previous one.
Esc - Exits and returns to DOS without saving modified screen.
Other keys - Use cursor keys to move around. Other keys generate
interesting characters (see Technical Reference).
Programs may not work with compatibles, do not work with a monochrome
display. Works on the PCjr!!! I've alos tested it out with following ram-
resident softwareand it works fine:
PC-DESKMATES (better than Sidekick but user-supported)
PEACOCK (Changes foreground and background screen colors)
RAMDISK (From Impulse)
KEYWORKS (Macro and menu maker)
I plan on using these tools to generate computer-based/self pacing tutorials
for the software we write.
