I don't know why the binder requires

could explain? Nobody here really understands CA-Endevor.
Is there any way that compiler output can be marked RENT? I thought
that option was available only on load modules.
If I knew CICS at all, would it be obvious to me why you don't simply
GETMAIN (whatever) a 72-byte save area?

Any native z/OS service that could potentially result in either a TCB
wait or ABEND is not acceptable in application transaction code that
runs in a multi-user transaction server region like CICS. GETMAIN falls
into that category, so CICS creates its own memory pools and provides
CICS memory management services which transaction code running under
CICS must invoke, partially to achieve lower overhead by taking
advantage of special knowledge of the transaction environment, but also
to allow CICS to degrade more gracefully than a total failure by
modifying transaction dispatching should the region begin to get
Short-On-Storage. Those CICS Server services are only available in a
CICS server region, not in batch, which complicates the design of any
subroutine which needs to run in both environments.
