I've been working on calling an (amode 31) assembler program from a 64 bit C program, and have been struggling.Is there is a good guide on how to use these new instructions? For example 1) I've found you need to use a LLGTR R1... instruction to clear the register before using a L R1... because without it the high part of the register will have some 64 bit rubbish in it
2) I used BAKR R14,0 PR But it kept returning in amode 24 bit mode. It needs BSM 14,0 before the BAKR.__ The POP tells you all about the instructions - but not how to use it. The z/OS doc says use BACK/PR without mentioning the BSM, so this is not completely trustworthy. _________________________ Is there a better place to ask?
