HEAP option used with the interface to CICS

In C/370™ V2, the location of heap storage under CICS® was primarily determined by the residence mode (RMODE) of the program.

With Language Environment® services, heap storage is determined only by the HEAP(,,ANYWHERE|BELOW) options. RMODE does not affect where the heap is allocated. If the location of heap storage is important, you might want to change the source code accordingly.
