Searching for a string in a list

Recommended syntax	Syntax with lower performance
/MATCH = SEARCH-LIST-INDEX(/ LIST-VARIABLE-NAME = X,/ PATTERN = P)	/LOOP: FOR I = *COUNTER(1,SIZE('X'),1) / IF (INDEX(X#I,P) <> 0) / SET-VARIABLE MATCH = I / EXIT-BLOCK LOOP / END-IF /END-FOR

The SEARCH-LIST-INDEX function was developed specially to improve performance. It searches through a list variable for a string or a regular expression in a call and returns the index of the first match. Using this function avoids the time-consuming search in a FOR loop.
