We performed such a comparison, exhaustively, at the transition from Assembler H to HLASM. Successfully. Perhaps once earlier, when we encountered and programmed around an Assembler H code generation bug that IBM was calling WAD. IBM finally repaired it by PTF (did a customer more influential than we finally report it?) A very cautious manager, learning that IBM had modified Assembler code generation, required that we perform such a comparison, circumvention in place, before and after PTF. When the comparison succeeded, we saw no need to remove the circumvention. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
