A good use for LARL is to set up the base register for the constants - and
maybe the modifiable data area if the program is not reentrant. LARL can
even be used to get the address of other control sections. But I think you
are trying to use LARL for everything.
A LARL reference to another control section is playing with fire
since the displacement of the CSECT being referenced can change at
Bind Time. Only a ACON can track the real location/displacement:
Since z/OS 1.7 (and even better in 1.8) the binder manages relative references
to external symbols as needed.
