He'd be EXecuting the SVC established by the breakpoint, but with a changed SVC number. Net: I agree he should probably use EXecute not STC, but if he's setting a breakpoint it would need to be on the EXecute, not the AP to avoid the problem you mentioned. -- Walt -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

If not, 047 abend is WAD. Of course Jim Mulder and others are correct. One last question - *where* is that AP instruction (object of STC)? Same A/S or within same/other program? If not - is that module(s) linked AC(1)? Bonus question: Are any SVC's (including MODESET) active / called during that abend?

Re: Strange 047 abend
It's not really all that strange for a debugger to abend on a program that runs ok w/o the debugger. I would try using the EX inst instead of the program modifying itself as prior poster is hinting.

And what does TSO TEST do if you EXecute a breakpoint SVC? It would seem an interesting case for it to get right. -- glen -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

With what you are doing, you could possibly cause ABEND047 (or all sorts of other abends) not on the STC instruction, but on the AP instruction, if you had set a breakpoint on the AP under TSO TEST. That could happen because you would be changing the SVC number in the SVC instruction that replaces the first two bytes of the AP for the breakpoint. That could certainly cause some head-scratching. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
Re: Strange 047 abend
>From memory, S047 could be from any restricted SVC, so your dump would finger a x'0A' op code. I used TESTAUTH at one site, as you might guess an authorised version of the TEST command. Is it generally available? Otherwise, if you can't make progress any other way, could you run it in a safe version of the normal environment?
