Stores the base memory pointer address of where the Heap is allocated which can be used with SYS(2600) to retrieve data from this allocated memory.

This value is -1 by default, and set when Allocate() is called - directly or indirectly from SetData().

You can use this address to manually retrieve data from the heap with SYS(2600) instead of .GetBytes() which is easier to use but less efficient.

lcData = SYS(2600, loHeap.nBaseAddress -1 + lnOffSet, lnCount)
