- MEMMAP
-
- 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:
-
- Memory MemMap (Version 2, May 89)
- Control Block Size
- Block [Bytes] Owner
- Segment Hex Decimal Segment Type Name

- 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 <unknown>
- that are reported fully under DOS 4.0. When used under OS/2 EE, DOS
- identifies itself as DOS 10.10 <kernel>.
-
- 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 <shell>, as shown above. The default size of this block is 160
- bytes.
