ABOUT GRTXT.EXE -- GRABBER's "TEXT" VERSION
--------------------------------------------
GRTXT is an alternative version of the GRABBER screen capture
program. It is an especially valuable tool for users who need to
capture character-based text images from the video screen direct-
ly to plain ASCII text files on disk.
While GRABBER can be used to capture both character-based text
screens as well as pixel-based graphic images to your disk in the
form of executable image files, GRTXT is designed to capture
character-based text screens exclusively. GRTXT also differs
from GRABBER in that GRTXT captures your screens directly to
plain-ASCII text files, instead of to the .exe format.
If your screen capture needs are mostly text-based, and you
require the ASCII format rather than the .exe format, then GRTXT
can be much more convenient to use than GRABBER. GRTXT creates
ASCII text files that are ready to use immediately, without
having to be processed first by the GR2ASCII conversion utility
which accompanies GRABBER.
GRTXT is installed and operated in much the same way as GRABBER,
and the two programs have a very similar look and feel. For the
most part, this documentation for GRTXT covers only the aspects
of GRTXT which differ from GRABBER. It is assumed here that you
have read the GRABBER documentation file (GRABBER.DOC) and become
familiar with that program's operation.
USING GRABBER and GRTXT SIMULTANEOUSLY
---------------------------------------
GRTXT is designed to be compatible with GRABBER. Both programs
can be installed in memory at the same time.
The default "hotkey" sequence for GRTXT is [Alt =]. That is, you
hold down the [Alt] key, press the equal sign key [=], then
release the [Alt] key.
GRTXT is designed to capture character-based text images exclu-
sively. If you press GRTXT's hotkey and hear a single low-
pitched tone on the computer speaker, this means that the video
screen is running in a pixel-based graphics mode, and GRTXT is
unable to capture the screen.

MODIFYING THE GRTXT HOTKEY
---------------------------
GRTXT allows you to modify your hotkey sequence from the default
[Alt =] to practically any other key sequence you choose. In
this respect, GRTXT is exactly like GRABBER. There is no sepa-
rate documentation here which covers the procedure for changing
your GRTXT hotkey. GRTXT uses the exact same hotkey procedures
as GRABBER. You can read about these in the GRABBER.DOC manual,
at page 30 and at Appendices A and B. (To view a list of valid
KEY= codes for GRTXT, use the command GRTXT KEY=?. To view a
list of valid SHIFT= codes, enter GRTXT SHIFT=?.)
GRTXT INSTALLATION OPTIONS
---------------------------
GRTXT accepts the following command-line switches. Each of these
optional switches (except for the APPEND option) is also avail-
able in the GRABBER program. For more complete details concern-
ing the purpose of these optional switches and how they work,
consult the section beginning on page 15 of your GRABBER documen-
tation which is headed "Grabber Installation Options."
Option: DEFAULTDRIVE
Purpose: Tells GRTXT to capture text screens to whatever drive
and directory path is the current DOS default. As with
GRABBER, this switch can substitute for the drive/path
parameter which is otherwise required to make GRTXT
stay resident in memory.
Option: MOUSE and NOMOUSE
Purpose: To enable and disable, respectively, GRTXT's recogni-
tion of the "mouse hotkey," which allows you to capture
your text screens by holding down both the left and
right mouse buttons for about two seconds.
Please note: The mouse hotkey function is available in the
GRABBER program as well as in GRTXT. If you have installed both
programs in memory simultaneously, do not use the MOUSE switch to
enable the mouse hotkey with both programs. Strange results are
almost guaranteed to occur, and it may even lock up your computer
when you use the mouse hotkey. It is acceptable to use the MOUSE
switch with either GRTXT or GRABBER, but not both.

Option: UNLOAD
Purpose: Removes GRTXT from your computer's memory. GRTXT
cannot be removed from memory if, after you initially
installed it, you loaded other memory-resident software
which is activated by any of the same hardware or
software interrupts which GRTXT uses. If you are using
GRTXT and GRABBER simultaneously, both programs can be
removed from memory, but only in the reverse order in
which they were initially installed. In other words,
"last in, first out."
Option: SOUND and NOSOUND
Purpose: To enable and disable, respectively, GRTXT's use of
sounds through the computer's speaker. When enabled,
the sounds accompany the on-screen filename prompts,
and are also issued to indicate the successful comple-
tion of a screen capture operation.
Option: PROMPT and NOPROMPT
Purpose: To enable and disable, respectively, GRTXT's on-screen
filename prompts. When the prompts are disabled, GRTXT
creates ASCII text files on your disk without asking
you first what each file should be called. Instead,
the program assigns a sort of "serial number" name to
each file that is created. These files are named
GRTXT000.TXT, GRTXT001.TXT, and so forth up to
GRTXT999.TXT, at which point they return again to
GRTXT000. Please see also the section below dealing
with the APPEND command switch, and consult the de-
scription of the PROMPT and NOPROMPT options in your
GRABBER documentation for more important information.
Option: APPEND
Purpose: To enable the "Append Mode" when you have told GRTXT
not to use on-screen filename prompts by using the
NOPROMPT command switch. This option has no effect
when the filename prompts are enabled. If you do not
combine the NOPROMPT option with this APPEND option,
then GRTXT will work in its "Overwrite Mode," which
means that it will create a separate .TXT file for each
screen capture you request. However, when you do use
the APPEND switch, GRTXT creates only one GRTXTXXX
file, and appends each subsequent screen
capture to it.
GRTXT(tm) Documentation Page 5 of 5
Option: SWAPMODE
Purpose: To enable "DOS Swap Mode" of operation, which can
eliminate some of the delays you may experience in
getting GRTXT to pop up after you press the hotkey. The
SWAPMODE switch is valid only when you are initially
installing GRTXT in memory, and has no effect after the
program is already resident. For more information
about this option, see page 18 of the GRABBER.DOC file.
Option: BATCHCAPTURE or BATCHCAPTURE:filename
Purpose: Allows screens to be captured from within a batch file,
without having to press GRTXT's hotkey combination at
the keyboard. These options function exactly the same
way as they do in the GRABBER.EXE program. For a
complete description of how they work, consult page 19
in the GRABBER documentation.
GRTXT AND FILENAME PROMPTS
---------------------------
Probably the most significant difference you will notice between
GRTXT's interface and GRABBER's is in the area of the on-screen
filename prompts.
Unlike GRABBER, GRTXT does not offer a default filename sequence
such as GRTXT000, GRTXT001, etc., when it displays the prompts on
your screen. The first time you call up GRTXT after installing
it, there is no default filename present. You must supply your
own.
After your first .TXT screen capture, however, subsequent file-
name prompts will offer you a default filename which is identical
to the previous one you specified. You may accept this default
filename by pressing <Return>, or you can enter another name.
After you press <Return>, you will then see this additional
prompt, which is not present in GRABBER:
FILENAME exists -- (A)ppend, (O)verwrite, (C)ancel ?
If you wish to retain the contents of FILENAME.TXT and simply
append the current screen to the bottom of it, just press <A> or
<Return>. If you wish to overwrite (i.e., erase and replace) the
contents of the original FILENAME.TXT file, then press <O>. If
you decide not to work with this name and wish to enter a differ-
ent name instead, press <C>.
