AH = 83h AL = function 00h get size 01h set new size BX = new size in paragraphs
Return:
CF clear if successful BX = current size (function 00h) or old size (function 01h) CF set on error AX = error code (01h,07h,0Dh)(see #01680 at AH=59h/BX=0000h)
Desc: Specify or determine how much memory may be allocated by the foreground process
Note: 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)
