TERMS OF USE
This release and all subsequent releases of PSPLUS are hereby in

you are currently using or distributing the first release of this software,

the old release from your file system. This work is still copywritten.
WHAT *IS* PSPLUS?
Print Screen PLUS (PSPLUS) is a specialized memory resident Shift-PrtSc
driver. When installed into memory, it allows you to print the text screen to
the printer or save the screen to a file. Unlike other save-to-file programs,
PSPLUS prompts for a path and filename, and it has a special delayed-save
feature, which won't do any disk access until the system is free to allow it.
LIMITATIONS
Because PSPLUS does direct access to the screen, it is necessary to
have a graphics card capable of displaying in CGA 80 column text mode, although
it will work for any graphics card with text video RAM at b800 hex. It also
does low-level BIOS calls, which means that your computer's BIOS must be
IBM-PC compatible. When installed, it eats up just over 4K of RAM.
TO INSTALL PSPLUS
To install, simply type 'PSPLUS' at the DOS command prompt. There are
no command line options.
TO USE PSPLUS
To activate, press 'SHIFT+PrtSc' (Hold down the SHIFT key while
pressing the PrtSc key). Some keyboards use a slightly different notation than
'PrtSc' Look at your keyboard, or consult your computer's manual for locating
this key, if necessary.
A Menu will pop-up in the bottom right-hand corner of your screen.
From here, all functions of PSPLUS can be accessed. Simply press the key in
between the <> marks to execute that function (Ex: <P>rint screen).
MENU OPTIONS:
ESC-Exit
Press the ESC key (or any other un-defined key, for that matter) to
leave PSPLUS and return you to your application. This is great if you
accidentally hit 'SHIFT-PrtSc' (No more turning on the printer and wasting a
sheet of paper, not to mention time!!!)
<P>rint screen
Pressing <P> will immediately print the screen to the printer connected
to LPT1. (It uses the built-in ROM routine [Int-5].)
<S>ave to file
The <S> command causes a copy of the screen to be stored in memory.
When it is 100% safe to do so, PSPLUS will pop-back up on the screen, prompt
for the filename, and then save the stored screen onto disk. This is the most
powerful feature of PSPLUS. Note that when you press the 'S' command in the
middle of some programs, PSPLUS will exit and it looks like nothing
happened...Don't worry, PSPLUS will pop-back up on the screen when DOS is
ready, and save the screen for you.
When the filename window comes up, you can type just a filename, or a
complete path plus a filename. Pressing ESC (or <CR> on an empty line) will
abort the save.
Unfortunately, due to the nature of DOS, it can be a pain to save a
screen using this method, because you need to exit your program (or shell to
DOS) in order to save the screen. Thus the next command...
<I>nstant save
WARNING! NEVER USE THIS COMMAND IF THERE IS *ANY* SORT OF DISK ACCESS
OCCURRING, OR IF YOU ARE NOT SURE WHETHER OR NOT THERE IS ANY DISK ACCESS
OCCURRING...DOING SO WILL CAUSE YOUR SYSTEM TO CRASH...GUARANTEED!!!
The <I> command will immediately save the screen to disk...It will not
wait until it is 100% safe to save...It is up to YOU do decide when it is safe
to use this method. It is safe to use this method during any application, as
long as the application isn't in the middle of a disk operation. I apologize
for the redundancy, but it is VERY IMPORTANT to be clear on this matter.
For example, if you use the <I> command during the display of a DIR
command you will cause a nice system crash (you have to turn the power off,
then back on (or hit the reset button), if you accidentally cause this to
happen), however if you use the <S> command there will be no problems.
The <I> command is nice when you are in the middle of an application in
which the <S> command won't save unless you shell to DOS, and it is not
convenient (or possibly possible) to do a shell to DOS and force the screen
save. The usual procedure is try a <S> first, and if it doesn't save, and you
are *SURE* that there is no disk access, then use the <I> command.
Thank you for using this product. The author welcomes comments and
suggestions.
