Menu Option Functions

To help reduce the amount of CL programming required to set up an application system, the menu display program has three standard functions available, which can be specified for any option:

• Prompt the option: when the option is taken, the command specified as the option request will be prompted for some or all parameter values. This facility is mainly for use with commands. Note that selective prompting can also be used to protect particular parameter values. See the i OS Programmers Guide for details on the use of selective prompting.
• Submit the option: when the option is taken, the request associated with the option is not to be executed immediately, but rather is to be submitted to a batch queue. This feature can assist in development, performance tuning, and problem finding, since the function that determines whether a program runs in batch or interactively can easily be changed at any time.

  The job description used by the menu program to submit jobs can be specified as a parameter (JOBD) on the Toolkit command Go to Menu (YGO).

  You may specify for the option either:

  — Y: The values on the specified job description are used to route the job.

  — J: The job description values are overridden with values from the current interactive job. This can be used, for instance, to ensure that the submitted job had the same library list as the submitting job. The following values are overridden: INLLIBL, SWS, OUTQ, OUTQLIB, DATE, INQMSGRPY, LOG, Color

• Confirm the option: when the option is taken, an answer to an additional confirmation prompt will be requested before the option request is executed.  The confirmation prompt can require positive action either to confirm or to cancel execution. Thus:

  — CONFIRM Y: Positive action to cancel.

  Pressing ENTER will confirm execution.

  Typing N will cancel.

  — CONFIRM N: Positive action to confirm.

  Pressing ENTER will cancel execution.

  Typing Y will confirm.
