Rick, if you actually allocate storage (say using the ALLOC opcode),
memory is not released when the subprocedure ends.  The only time
ALLOC'd storage might be released unexpectedly would be if the
activation group it was allocated in was reclaimed (this would happen on
exit for a *NEW program, but never for a procedure).

You may have been passing back the address of a local variable in your
procedure.  That would behave the way you describe.
