I posted the original question and below is the response I received from
Alexei Pytel (top man in my opinion as this solution worked beautifully)

>> All heap support used to be limited to 16meg maximum allocation.
>> In V4R4 (it could be V4R5 - I am not sure) a new teraspace support was
>> introduced, which can handle much larger allocations.
>> Check compiler documentation in AS/400 information center.
>> Quote from the book "ILE C for AS/400 Programmer's Guide" - Version 4
>> Document Number SC09-2712-01 Part Number 24L2113 Program Number 5769-CX2:
>>      2. Objects built with TERASPACE(*YES *TSIFC) will allocate dynamic
>> storage from
>>     teraspace. Teraspace allocation routines do not use the _HEAP_SIZE
>> macro.
