Thanks all. 1. Source language is C++. I know how to call an "assembler" function from C++. It seems odd to me that IBM would make such a basic OMVS function available to assembler programs but only "by the way" available to C programs, but whatever.
2. Definitely no Rexx involved. 3. I have this nagging fear that the problem is that because the program is compiled #pragma RUNOPTS(POSIX(ON)) that as a result LE is failing it before my first "user" instruction executes, and therefore I have no ability to issue a more user-friendly message than a U4093 ABEND. I am trying to confirm that. I am currently wrestling with an internal "you can't get there from here" situation relative to testing with a no-OMVS-segment userid. Does anyone happen to *know* whether this is the case? That POSIX(ON) means LE requires an OMVS segment during program LE initialization? I wish IBM wouldn't do this. Logically, a U4093/90 ABEND is no different from an error message, but it does not work that way with customer psychology. We send out a trial package, the customer runs the product (and yes, we document the need for an OMS segment, but who reads documentation? Not our customers.) and it gets a U4093 ABEND. Does the customer look it up? No, he picks up the phone, calls the salesman and says "your product blows up when we try to run it." The salesman tells support. By then the customer has deleted the SYSOUT without noting the exact ABEND, so we have to persuade the disgruntled prospect to run the product AGAIN -- he inevitably reports "no better -- it's STILL blowing up" so we can get the ABEND code and diagnose the problem. In fact, get all of the symptoms because at that point we don't know that the ABEND number will be sufficient to diagnose the problem. A nice, readable message, either from LE or from us, would be a lot better all around. End of rant.
