Thanks Frank. I read over your email in detail. It sounds like a static CALL is the way to go.
It's a C++ calling our COBOL module. He mentioned an IBM BINDER 'binding' the calling and called modules together. I've never heard that term before. Is it a C++ term? Also, will the AS INITIAL cover the need for doing explicit initializations? I'd like to avoid the human error potential. Thanks!

Look back at my previous response about how to compile with the CICS(NOLINKAGE) option and how to CALL it. Works great! But wait; is the called module written in C/C++, not COBOL? If that is the case then I can't say for sure. I bet it is still possible, but I couldn't say for sure how it could be done.
