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
  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
  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.
