 HEAPSIZE
------------------------------------------------------------------------------
 Purpose:
 Set local heap size in bytes

 Syntax 16:
 HEAPSIZE  size | MAXVAL

 Example 16:
 HEAPSIZE 3000

 Syntax 32:
 HEAPSIZE reservesize [, commitsize]

 Example 32:
 HEAPSIZE 65536,4096

 This command sets the size of the program's local heap in bytes, and for 32
 bit programs also optionally sets the committed size in bytes.

 For 16 bit Windows the heap is created in the default data segment after
 DGROUP, so its maximum size is determined by the size of DGROUP. The keyword
 MAXVAL can be used to set the heap size of 16 bit programs to 64 Kb minus
 the size of DGROUP, i.e. the maximum possible size.
