Error description

  • When running under CEDF in single terminal mode, EXEC CICS
    RECEIVE MAP which is first BMS command on the task does not
    get MAPFAIL. The application get normal responce with
    residual TIOA of previous MAP. It casue incorrect output
    for the following EXEC CICS SEND MAP.
    

Local fix

  • Use dual terminal mode CEDF.

    *                      first EXEC CICS RECEIVE MAP command     *

    ****************************************************************
    An application is being debugged using CEDF in single terminal
    mode. The first program does an EXEC CICS SEND MAP followed by
    an EXEC CICS RECEIVE MAP then an EXEC CICS START TRANSID
    command. The started task does an EXEC CICS RECEIVE MAP command
    which is the first RECEIVE MAP in the program and it should
    return with MAPFAIL error but instead completes with a NORMAL
    response.
    CEDF checks the TIOA length for each new task and if it is not
    zero the TIOA will be saved and then restored for the first
    RECEIVE in a program. This will result in BMS mapping the
    restored data in the TIOA.
    However, for started tasks, TIOA length is zero so BMS does a
    real receive of whatever data is at the terminal which will be
    the restored user's display and the RECEIVE MAP completes
    normally.
    Even though the TIOA length for started tasks is zero it should
    be saved and then restored for the first RECEIVE. The first
    RECEIVE MAP would then fail because BMS will be mapping a TIOA
    without any data.

Problem conclusion

  • DFHEDFD has been changed to check if the task is a STARTED task
    and, if it is, save and restore the TIOA for the first RECEIVE
    if TCTTEDA has an address.
