The fact that your dump says DOWNSTACK DSA almost certainly implies XPLINK. In the LE Debugging guide where I went to verify this, there is this interesting note under "Finding XPLINK information in a Language Environment dump": "It is important to understand that the registers saved in an upstack DSA are those saved by a routine that the DSA-owning routine called. Typically register 15 is the entry point of the routine that was called, and register 14 is the return address into the DSA-owning routine. In contrast, the registers saved in an downstack DSA are those saved by the DSA-owning routine on entry. Register 7 is the return address back to the caller of the DSA-owning routine. Register 6 may be the entry point of the DSA-owning routine." Regardless, I don't think these are *your* registers at time of failure. > Regarding overlays, anything is possible but it's highly unlikely.

If you don't know TEST, I wouldn't start now... For one thing, the support for anything 64-bit is somewhere between none and minimal. But if you know TEST, then it should be possible to copy your executable (program object in a UNIX file) into a PDSE member and then run it under TEST. But then you won't have a UNIX shell, and who knows what else may be missing; it may take you down a rathole. But I *have* done this copy of a program that was written by non-MVS C programmers into a PDSE and run it under TSO successfully, so at least that part can work. Good luck.
