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.
