"Thank Steve, I only mentioned it because Bill had discounted the idea and I was pleased with your confirmation it was possible. :) "
"Discounted" for a reason. The AMBLIST outputs were compared. AMODE is in the heading. I'd be more than mildly surprised if the OS/VS COBOL program with an Assembler program last assembled in 1989 has an AMODE other than 24. With an AMODE of 24, how could you possibly get 31-bit-addressed IO areas from a COBOL program? On the available evidence, and subject to review if the evidence changed, I didn't discount it, I *utterly dismissed it*. Following a fluffy puppy up a country lane because in an entirely different situation (causes of S0C4 are hardly of a limited number of specific things) a fluffy puppy was the answer is... how useful? Multiple people concurring on a suggestion doesn't in itself make it any more valid. In other situations it is spot on, but here? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
