Parameter Entries
Use the Parameter Entries section to change the elements of a delimited list.
The contents of the Entries field must use this syntax:
param, [delimiter,] pos = scalarExpr
where:
- param is the name of an event parameter that contains a string comprised of zero or more elements separated by the delimiter character.
- delimiter is the character or string which separates elements in param from each other. This argument is optional. If this argument is not used, the comma (,) character is used. In this case, each element may contain commas if they are enclosed within a ~LIT~(…) wrapper.
- pos is the 1-based position of the element to change.
- scalarExpr is the value to whose string representation the element is to be set.
If multiple elements of the same parameter are to be changed, include their positions and values as additional entries separated by commas, for example:
param, [delimiter,] pos1 = scalarExpr1, pos2 = scalarExpr2[, ...]
When you click Event Actions form, the system "wraps" this content within a SETPARMENTRIES( ) parameter, which yields this final syntax:
to return to theSETPARMENTRIES( param, [delimiter,] pos = scalarExpr[, …] )
Note: If any scalarExpr is a literal value, the system automatically encloses
it in double quotation marks when returning it to the Event Actions form.
If a scalarExpr is an expression, the system does not enclose it in
quotation marks.
