GRABBER is a screen capture utility for DOS, developed by Gerald (Jerry) A. Monroe.

Images are saved as self-displaying executable files. Older versions use COM format, and newer versions use EXE.

[edit] Discussion

Some of the registered versions have major version number 5 or 6, though they aren't necessarily newer than the 3.x shareware versions. This is mentioned in, for example, the REGISTER.DOC file from the 3.98 distribution.

GRABBER may require a fairly accurate DOS emulator or a VM, like VMware Player. Versions that seem to work in DOSBox are 2.10 through 3.35, and 3.84 through 3.91. Versions that seem to work in VMware Player are later ones (like 3.98). Earlier versions like 3.34 doesn't support VMs (it captures garbage), but works fine in DOSBox.

In INNARDS.COM in GRABBER 2.10 (with samples), there was a earlier 2.0 release (from 1987), but it hasn't been located. Magic numbers are:

GRABBER Ver. 2.0 Drive ë:

and:

[edit] Format details

The default save filename for v2.10 to v3.00 is "SCREEN_A.COM", "SCREEN_B.COM", etc. For v3.20 to 3.35, it's "SCREEN00.COM", "SCREEN01.COM", etc. For v3.60 to 3.96, it's "SCREEN00.EXE", "SCREEN01.EXE", etc. Later versions try to derive a name from the running program, or "MSDOS00.EXE"... if there isn't one, or "SCREEN00.EXE"... as a last resort.

[edit] Identification

Information based on minimal research. May not be correct for all files.

v2.10-2.20 (COM format): No readable signature. The first 16 bytes are

fb be 81 00 8a 4c ff 30 ed 09 c9 74 20 56 fc ac

v3.0 to 3.30 (COM format): There's a string at offset 5 that's either

All Code Copyright (C) 1988 Gerald A. Monroe

or

All Code Copyright (C) 1988, 1989 Gerald A. Monroe

v3.34-3.35 (COM format): There's a string at offset 5 that starts with

This file was created by GRABBER.COM Version

EXE files have ASCII "Created by GRABBER" at offset 49.

-Images are saved as self-displaying executable files. Older versions use [[DOS executable (.com)|COM]] format, while newer versions use [[MS-DOS EXE|EXE]]. The switch to EXE happened sometime between v3.35 and v3.60.
