Abstract

moss finds occurrences of substrings matching a pattern in a given string variable. Depending on what is sought and what is found, variables are created giving the count of occurrences (always); the positions of occurrences (whenever any are found); and the exact substrings found (when a regular expression defines a subexpression to be returned).
