EPDM - New Input Formula Function "String X from List"

In the functions added for input formulas on data cards (thanks SolidWorks!), there is one called "String X from List." When you choose it, it puts the following text in the input formula box, \$Token(AAA|BBB|CCC|DDD,2,|). I didn't find any documentation on this function. How is it supposed to work?
