Okay, you got me curious about this. I guess the "short" DCB is the EXCP DCB?
Looks like the MACRF flags (x'32' before OPEN, x'2A' after OPEN) say X'80' -DCBBIT0- EXECUTE CHANNEL PROGRAM (EXCP). ALWAYS ZERO (BSAM, QSAM, BPAM, BISAM, QISAM, BDAM). RESERVED (QTAM, BTAM) So I would say "short DCB" is implied by an X'80' bit being on in MACRF.

Perhaps its the fact that NO flags are set in the short DCB at fields DCBMACR (in FOUNDATION BEFORE OPEN ) and/or DCBMACRF (in FOUNDATION AFTER OPEN)? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
