<p><b>Desc:</b>
Specify or determine how much memory may be allocated by the foreground
process
<p><b>Note:</b>
If the partition size is set to 0000h, no partition management is done
and all memory allocation is compatible with DOS 3.2..
The partition size can be changed regardless of what use is being made
of the changed memory; subsequent allocations will follow the
partition rules (foreground processes may allocate only foreground
memory; background processes allocate background memory first, then
foreground memory)
