Running a program in a subspace

z/OS MVS Programming: Extended Addressability Guide
SA23-1394-00

A program running in a subspace will abnormally end if it attempts to reference:
  • Storage that is assigned to another subspace
  • Storage that is eligible to be assigned to another subspace, but is not assigned.

Aside from these restrictions, a program running in a subspace can reference the same storage that a program running with full address space addressability can reference.

The following topics describe additional considerations for a program running in a subspace.
