The heap identifier supplied in a call to CEEGTST or CEEDSHP did not match any known heap identifier, or the heap had already been discarded by a call to CEEDSHP (discard heap) before the request.
No storage is allocated. The value of the address parameter is undefined.
For get heap storage requests, ensure that the value in the heap identifier parameter is either 0, indicating the default heap, or an identifier returned by the CEECRHP (create heap) service. For all other requests, ensure that the heap is not discarded before the request.
