System Memory Map

This program analyzes the DOS storage chain and produces a summary report of
the resident DOS extensions. DOS 2.0, 2.1, 3.0, 3.1 are required to use this
program. Allocated storage starting with the resident portion of Commmand.Com
is displayed. The following information is provided for each resident program:

The PSP address
The program name (if available)
Allocated segment count
Total allocated memory (in bytes)
Hooked interrupt list

In addition, MAP displays the count and size of 'FREE' storage segments in the
DOS chain and the current command load address.

Plus you get the ROM BIOS date and the Machine type (as encoded in the BIOS).

If you us the '/D' switch after MAP (example: MAP/D) then you will get a
detailed display which identifies the specific segments (PROGRAM block,
ENVIRONMENT block or PROGRAM MEMORY) that a process has allocated. Using
this option causes the free storage segment to be identified.

Have a good day!
