TSR Utilities Version 3.5

The TSR Utilities are a collection of programs useful for managing DOS
memory, particularly for managing memory-resident programs, also known
as TSR's. TSR stands for "Terminate and Stay Resident". The most popular
use of these utilities is for removing TSR's from memory without
rebooting the PC. There are many other uses, however, especially if you
are a software developer.
The TSR Utilities have grown to include 11 programs. Here's a quick overview of each one:
MARK marks a position in memory above which TSR's can be
released.
RELEASE removes TSR's from memory.
FMARK performs the same function as MARK but uses less memory.
MARKNET like MARK, but saves a more complete picture of system
status.
RELNET removes TSR's marked with MARKNET.
WATCH a TSR itself, it keeps records of other TSR's.
DISABLE disables or reactivates TSR's, leaving them in memory.
RAMFREE shows how much RAM memory is available.
MAPMEM shows what memory resident programs are loaded.
DEVICE shows what device drivers are loaded.
EATMEM uses up memory for controlled program testing.
These programs are described in detail in the following sections. If you
haven't used them before, be sure to read this section first. All of the
programs are "command line driven," and unexpected events may occur if you
just start typing the program names at the DOS command line. Also be
sure to read section 7, "Known Limitations".
The most notable feature of TSR Utilities version 3.0 is support for MS-DOS 5.0 and TSR's loaded in high memory. If you are familiar with previous versions of the TSR Utilities, see the file TSR30.DOC for a summary of the changes in version 3.0. Version 3.1 cleans up bugs and compatibility problems discovered in 3.0. Version 3.2 of the utilities generalizes the high memory support so that it no longer requires DOS 5.0 or particular memory manager versions.
