Dan,
 
   GetHeap and RtnHeap are both documented in the Pascal/3000 reference
manual (Compatibility mode).
They allocate space from the DL-DB area and are NOT compatible the DLSIZE
intrinsic (i.e. Don't mix DLSIZE with these calls in the same program).
 
The have the same parameters: logical pointer, integer, logical.  All 16 bit
by reference:
 
Parm1 is pointer to region to be allocated or freed
Parm2 is size requested/returns actual size allocated or freed
Parm3 is status (must be 0 on input and returns non-zero if the function
wasn't completely successful)
 
Manual status you must free the same amount of memory you allocated, not a
part of it.  Can't be used in BASIC/3000.
