The context was using BPAM with a single OPEN versus doing multiple OPENs. BTW, since the OPEN exit is called with a SYNCH, why was the AMODE on return an issue?

At the advent of SDB I wondered why that didn't exist around 1965. Lots of gyrations to switch to AMODE 24 for access methods, and restore caller's AMODE without program check on 370. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
