If you do an IPCSDATA ACTIVE subcommand under IPCS, you should find in there
DATA STRUCTURE(Tcb) FIND(BLSSTCB) FORMAT(IEATCBF) SCAN(BLSVTCB)
EXIT CBSTAT(TCB) EP(BLSAFLG)
EXIT CBSTAT(TCB) EP(IEAVTRCA)

EXIT FORMAT(TCB) EP(IEAVTFMT)

EXIT FORMAT(TCB) EP(ICHIXTCB)
It is the EXIT FORMAT(TCB) EP(IECDAFMT) that drives this data management
formatting.

I see TIOT (does that include XTIOT?) but not DCB, DECB or IOB, and I would
have expected any new support for them to be via VERBEXIT.
Do you have a sample output? Thanks.

Yes, Wayne Rhoten enhanced that a while back. I don't remember which release
of z/OS, but I have gotten accustomed to seeing it in the output from the
SUMMARY FORMAT subcommand.

Subject: IPCS formatting of I/O control blocks
The last time I looked, IPCS did not format, e.g., DCB, DECB, IOB. Has that
changed?
