index

This function returns a text string containing the index into the v[ ] array of text strings that corresponds to the element of v[ ] that matches the contents of the input text string.

Syntax

index( input,v[ ])

Parameters

• input—Specifies the input text string.

The input text string can be another field mapping grammar function.
