Specify a value that allows the function to determine exactly which action bar choice was used to cause the function to be invoked. The value you specify here is placed into field AB$OPT when this menu option is used. This field is accessible to RDML functions.
Value specified should be unique within this action bar.
It is an alphanumeric value.
Do not use values CUR or ALL as they are reserved to mean "current" and "all" in the SET_ACTION_BAR Built-In Function.
If AB$OPT is not already defined in the Repository, define it as alphanumeric (length 3).
Tips & Techniques
One RDML function handling multiple action bar 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 AB$OPT values should be established.
