Problem conclusion

  • ITPGENCB: Set RPL6USR=TPIIACNP so TPC CB is available
              to ITPVTAPP. Do not use TPIIACNP to reference
              other CBs if it is null.
    ITPVTAPP: Move reset of RPL & RPLX RCs to ENQVST before
              Queue to ITPVTAM.
    ITPGENCP: Verify conversation ID using TRT table ITPZNUM.
    ITPAPCNO: Blank out network ID in CNOS CB if not set.
    ITPDATE:  Eye catcher.
