A general answer is Yes. Heap data persists until you explicitly free it. Stack data "pops" when you return from a called routine.
That's a general answer. I don't know your specifics, and everything I know about pointers in COBOL could be engraved on the back of a postage stamp. But in general, routine X can call routine Y passing a pointer variable. Routine Y can then allocate something on the heap (malloc or new) and place the address in the pointer variable. On return to X, the allocated area is (still) available to X.

I want to have a Cobol program call a C routine, the C routine to place data onto the heap then return back to Cobol. The question is can Cobol then reference that data ?
