I'm using, don't ask, the V2.3.0 Optimizing Compiler on, don't ask, z/OS 1.10 ADCD running under, OK enough.
I've managed to find out that the library routine to print the COUNT table is IBMFEFCA, by doing a SRCHFOR for "GRAND", and by copying it into my ISPPLIB, I've actually got a disassembly via the DISASM function of ISRDDN. Now I just need to know how many and which of the, I guess, three BNP instructions need to be changed into a BNZ, and yes, even a complete assembler noob like me can do that without the usual tools. If anyone (privately) likes to help me, feel free to contact me in private. Robert On Sun, 19 Jun 2022 at 17:42, Seymour J Metz <[email protected]> wrote: > Is it the same in Version 2?
