765

Abbreviation for terminate-and-stay- resident. A TSR program runs “in the background.” Most TSR programs imple- ment a predefined key combination (sometimes referred to as a “hot key”) that allows you to activate the TSR pro- gram’s interface while running another MS-DOS program. When you finish using the TSR program, you can return to the other application program and leave the TSR program resident in memory for later use.

Because MS-DOS is not designed to support multiple programs running simul- taneously, TSR programs can sometimes cause memory conflicts. When trouble- shooting, rule out the possibility of such a conflict by rebooting your computer with- out starting any TSR programs.
