Paul, Is there any reason why you are avoiding UCBSCAN and then a test for UCBONLI ?
If so, then I suppose you could consider doing the UCBSCAN once (at init) and then use an ENF listener (codes 23/24/30) to update your table of units. However, this might seem a little extreme just to avoid UCBSCAN...

Let me further expand: I do a EDTINFO RTNDEVN,UNITNAME=xxxx,DEVNLIST=DEVNLIST to (for example) get the list of device numbers associated with UNIT=SYSALLDA. All of these device numbers will have a UCB associated with them, but many are 'dummy' UCB's that have no real volume associated with them. (These are UCB's that have been genned for future DASD expansion.) Does doing a EDTINFO CHKUNIT,UNITNAME=xxxx,DEVLIST=,DEVCOUNT=,DEVSTAT= provide me the status if a real UCB is at that device # address? What I'm trying to accomplish is to build a list of on-line UCB's. I know I can do a UCBLOOK on each of the device #'s returned with the EDTINFO RTNDEVN macro and then check if the UCB is online, but I am looking for something faster.
