FINDENVB is reliable. It's designed for languages that don't have access
to R0. I use it in all my REXX command processors written in C++.

I would guess that FINDENVB is no better, no different really, than passing 0 and letting
IRXEXCOM take a guess. Am I wrong? The way I read the docs is that method will fail if
the caller is using a Rexx "reentrant environment." Am I wrong?

There is a field in the LE Enclave Control Block called CEEEDB_R13_PARENT which is a
pointer to a DSA containing the registers of the enclave parent. If you can be bothered.
I would just use IRXINIT("FINDENVB ") to get the environment block as opposed
to fiddling about with control blocks.
