GET-PCX version 1.03 by Mike Williams
-------------------------------------
GET-PCX is a screen-grabber that captures most standard screen modes,
saving them into a standard PCX file. The file will be saved on the
drive and in the directory that was current when GET-PCX was loaded,
using the name PIC00000.PCX, PIC00001.PCX, PIC00002.PCX etc.
If the name matches an existing file then GET-PCX tries a higher
number; it will never overwrite an existing file.
The Basics ...
--------------
Syntax: GET-PCX [/BLOAD] [/U] [/NODISK] [/NOEMS] [/QUIET] [/Kx]
/BLOAD : Save text screens in BASIC BLOAD format
/U : Unload from memory ( if possible )
/NODISK : DO NOT swap TSR code to disk
/NOEMS : DO NOT swap TSR code to expanded memory
/QUIET : Disable various beeps
/Kx : Specify hot-key where:
x Key
0 Ctrl-Alt-S (Default)
1 Left Shift-Right Shift-S
2 Ctrl-Alt-P
3 Left Shift-Right Shift-P
4 Ctrl-Alt-G
5 Left Shift-Right Shift-G
The Details ...
---------------
/BLOAD
If you've ever programmed in BASIC, you may have come across the
BLOAD statement. Basically, it enables the programmer to load the
contents of a disk file directly into a block of memory. Mostly
this is used for saving and loading screens. By specifying the
BLOAD switch when you load GET-PCX, you instruct the program
to save text-mode screens in a Basic-compatible format. You can
then load them directly in your Basic program.
If you do NOT use the BLOAD switch, then the screen is saved
in a straightforward memory-image format.
/U
When you have finished using GET-PCX, you will probably want to unload it.
The /U switch will attempt to do this for you. It may not be possible to
unload GET-PCX if you have loaded another TSR in the meantime.
/NODISK /NOEMS
GET-PCX saves RAM on load-up by swapping most of its code out to expanded
memory. If insufficient memory is available, disk space is used instead.
When the hot-key is pressed, GET-PCX swaps itself into memory, saves the
current screen, and swaps back.
Unfortunately, this kind of behaviour is unappreciated by some applications,
and can result in a system lockup. If this happens, try using /NODISK
and/or /NOEMS and see if the problem disappears.
Note that, when installing GET-PCX in a DOS box under Windows, saving
to EMS is automatically disabled.
/QUIET
In order to inform you that everything is working, GET-PCX issues a number
of rising notes when it pops up, and descending notes when it pops down.
Clever, huh ? This is actually of some use, because it may be the only
visible sign you have that anything has happened. However, if you have
a particularly loud speaker on your PC, or particularly irritable colleagues
at the next desk, you can disable all the beeps by using the /QUIET switch.
/Kx
By default, GET-PCX is activated by pressing CTRL-ALT-S. ( That is, hold
down CTRL and ALT, and press S ). If this happens to intefere with the
application you are using, you might want to use a different keypress.
Those available are
x Key
0 Ctrl-Alt-S (Default)
1 Left Shift-Right Shift-S
2 Ctrl-Alt-P
3 Left Shift-Right Shift-P
4 Ctrl-Alt-G
5 Left Shift-Right Shift-G
So, to set the keypress to left shift+right shift+P, you would use
GET-PCX /K3
The Video Modes.
----------------
GET-PCX ought to work ( ! ) on these video modes .....
Text Mode - 80x25, 80x43, 80x50, 40x25, 40x43, 40x50.
Other row/column combinations will PROBABLY work, if they
correctly inform the BIOS of what they are doing.
Hercules - 720 x 348 x 2 colours ( well, black and white anyway )
CGA - 320 x 200 x 4 colours
640 x 200 x 2 colours
EGA - 640 x 350 x 16 colours ( actually 64 colours, if you've got
enough video RAM )
VGA - 640 x 480 x 2 colours
640 x 480 x 16 colours
320 x 200 x 256 colours
The Legal Stuff.
