6.5.6 PD$OPT

Mandatory.

Specify the value that allows the function to decide exactly which pull-down choice was used to cause it to be invoked.  The value specified here is placed into field PD$OPT when this pull-down choice is used. The field is accessible to RDML functions.

Rules

• Value specified should be unique within this pull-down, and preferably, within the entire action bar.
• It is an alphanumeric value.
• Do not use values CUR or ALL, as they are reserved to mean "current" and "all" in the SET_ACTION_BAR Built-In Function.

Warnings

• If PD$OPT is not already defined in the Repository, define it as alphanumeric (length 3).

Tips & Techniques

• One RDML function handling multiple pull-down choices can have good performance implications. Refer to the Sample Program: All 3 Functions in One Program in the LANSA Application Design Guide.
• Standards for PD$OPT values should be established.
