GRABBER
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.

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. Versions that seem to work in DOSBox are 2.10 through 3.35, and 3.84 through 3.91.
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.
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
v3.20 to 3.30 (COM format): There's a string at offset 5 that's either

or

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