Re: Simple assembler question

Thanks to all who replied; the use case is returning a 64-bit value to a C function, which LE does by putting the top half in R0 and the bottom half in R15. Which is weird but is how it’s done. So I don’t much care about the top halves, nor bit 0 of the 32-bit register, but thanks for the

Re: Dynamic enqueue creation

So the option of listing datasets, then calling a batch job with DISP=OLD in the last step also means that there's a gap between the submit and the dataset listing. Since I did the listing and "alloc fi(Fn) old" part in REXX, it's only held as long as the REXX runs. I may end up having to wrap

Hello Walt and Paul, Thanks for your ideas. This is to cope with MQ FTE's "feature" of not locking datasets for the duration of a transfer. Using ANT scripts to initiate a transfer of a list of datasets that resolve to a wildcard, we've found that in the time gap between the initial resolve

Phil, You may want to use LLGTR instead of LR, as LR will leave the high half of R15 as it was, while LLGTR R15,R3 will zero the high 31 bits of R15 then copy the low 31 bits from R3 into R15. == Wayne Driscoll OMEGAMON DB2 L3 Support/Development
