Congratulations; you've invented OS/VS1. I'd also like to see that for DSORG=PO, with ACB-based equivalents to BLDL, FIND and STOW.

You didn't ask for that. I think that you are assuming that is is > trivial. > What I thought about, but haven't ever throw out here for discussion, is the idea that IBM should create a new "subsystem" accessable via the SUBSYS= on the DD which would allow accessing PS type data sets via an ACB. What I envision would be that when the subsystem DS was OPEN'd, the subsystem would load an I/O routine into RMODE(24) storage and dynamically create a DCB & new DD statement with the same DSN. Then a GET or PUT via the ACB would invoke the I/O module appropriately which would switch to AMODE(24) and the the actual QSAM/BSAM I/O. This would allow at least the majority of the uses people have for PS type datasets to use this interface from AMODE(31) or AMODE(64) routine in a consistent GUPI manner which everybody in the industry doing it the same way, rather than "ad hoc". > > Are you also assuming that they will accept an address above the bar for > parameters? > > -- > Tom Marchant > > ---------------------------------------------------------------------- > For IBM-MAIN subscribe / signoff / archive access instructions, > send email to [email protected] with the message: INFO IBM-MAIN > -- We all have skeletons in our closet.
