- ClrTSR is a small system of two programs that can be used
- to manage memory-resident programs. TSR stands for "Terminate
- and Stay Resident". The two programs are are used simply
- as follows:
-
- 1) Call the program MARK.COM before installing any memory-
- resident program that you may wish to deinstall later.
- This marks the current position in memory and stores the
- DOS interrupt vector table (all interrupts from 0 to FFH).
-
- 2) Install whatever TSRs that you want to use in the normal
- way that you install them.
-
- 3) When you want to deinstall all TSRs above the last MARK,
- call the program RELEASE.COM. This will release all of the
- memory above (and including) the last MARK, and restore
- all interrupt vectors taken over by the memory resident
- programs.
-
- MARK and RELEASE can be "stacked" as many times as desired.
- RELEASE always releases the memory above the last MARK called.
-
- MARK and RELEASE should work on any system running PCDOS or
- MSDOS 2.0 or later. They were developed on a Compaq Deskpro
- 286 running Compaq DOS 3.0.
-
- Get the program MAPMEM.COM (or MAPMEM.PAS) to display the
- current DOS memory map at any time. Get the program EATMEM.COM
- or EATMEM.ASM for development work where you want to test
- software in an environment with a desired amount of available
- memory.
