The No File Updating Option

As we did when we set and removed the MXR and MXS options, bring up the Program Monitoring screen. For convenience, use the CA InterTest for CICS fast path feature to navigate to this screen.

  1. Type SO on the command line and press Enter.

    The Special Options menu appears.

  2. Tab to the NUP field.
  3. Type an x, and press Enter.

      SET  one or more options to override the default monitoring rules in:

    CA InterTest for CICS sets this option for the demo program.

  4. Type =x in the Command field and press Enter to return to the Source Listing Breakpoint screen.

    Before resuming program execution, look at the statement just before the EXEC CICS REWRITE command:

    NUP_NAME = 'THIS IS NOT A NAME'

    PLIDEMO is supposed to move the data string THIS IS NOT A NAME to the data field NUP_NAME. If PLIDEMO actually updates the file, this data string displays at the beginning of the first record in that file.

  5. Press PF5 to continue program execution.

    The demo program resumes execution.
