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, while newer versions use EXE. The switch to EXE happened sometime between v3.35 and v3.60. The default filenames for v3.x are "SCREEN00.EXE" (or "SCREEN00.COM"), "SCREEN01.EXE", etc. For v2.x, it's "SCREEN_A.COM", "SCREEN_B.COM", etc.
