KEYS is a keystroke stacking program compatible with the 4DOS KEYSTACK command. It can be used as a replacement for the 4DOS KSTACK utility. KEYS comes with complete source, has a smaller resident size than the 4DOS KSTACK program, implements a more flexible command line syntax than the 4DOS KEYSTACK command, and is freely redistributable. KEYS can be used to load keystrokes into the 4DOS KSTACK program, to take advantage of the more flexible command line syntax, or can be used to replace the KSTACK program (and the 4DOS KEYSTACK command will happily load keystrokes into KEYS) to take advantage of the smaller resident size. Keystroke stacking is useful to automatically control programs that otherwise demand keyboard input. Up to 110 keystrokes can be stacked from the command line or 255 from a redirected input file (STDIN). Uploaded by author, glenn.linderman@sandiegoca.ncr.com. Similar to keystf.zip, stackey3.zip, stfkey15.zip in effect (all these are found in batutil). Can be used as a replacement for KSTACK (part of 4DOS).
