It is (properly) documented that SETFRR supports only invocation in AMODE 24 and AMODE 31.
This might change in a future release, but there is very slim benefit to do that. In that release, invocation in AMODE 64 would result in your FRR being given control in AMODE 64. There are many branch-entry services that do not support AMODE 64 invocation. SETFRR is one. You need to switch to AMODE 31 before invoking it. Regarding ESTAEX, it is documented that ESTAEX may be issued in AMODE 64. If that is done, your ESTAEX routine will get control in AMODE 64.
