I know that I've seen somebody do this before. But I cannot remember how they

You want to make sure you are not creating and destroying a LE
environment for every call, or it will get expensive.
If your calling Assembler program is Language Environment-conforming,
have a look in "z/OS V1R12.0 Language Environment Writing ILC
Applications", section "14.5 Assembler Main Call
