Purpose: To display all allocated memory blocks, including memory-resident
(TSR) programs and their associated environment memory blocks.
Optionally, also displays the the variables in each environment block.

Format: MEMMAP [/V]

Remarks: Entered at the DOS prompt without its optional /V parameter, MEMMAP
produces a display similar to that shown below:

Note that under DOS 2.10, 3.3, and the DOS Command subset of OS/2
Extended Edition 1.1 some program names will be designated
that are reported fully under DOS 4.0. When used under OS/2 EE, DOS
identifies itself as DOS 10.10 .

Entered with the /V switch, MEMMAP also reports the environmental
variables that are loaded with each TSR. These variables initially
loaded by DOS are contained in the first environment block with the
name , as shown above. The default size of this block is 160
bytes.
