Make sure that the data you are sending to the AMODE 31 program resides in AMODE 31 storage. I had this sort of problem when we first when from AMODE 24 to AMODE 31. Also, remember that BASR does not affect the addressing mode. So if you are in AMODE 64 before the BASR, you are still in AMODE 64 in the other module. To branch and change AMODE, you need to use the BASSM. And your AMODE 31 code needs to use BSM to return, not BR! Otherwise, you'll need to use a sequence like SAM31, BASR, SAM64 to switch AMODEs in your AMODE 64 code. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
