Have a look at the "index" function: 
index STR,SUBSTR,POSITION
        The index function searches for one string within
        another, but without the wildcard-like behavior of a
        full regular-expression pattern match.  It returns
        the position of the first occurrence of SUBSTR in
        STR at or after POSITION.  If POSITION is omitted,
        starts searching from the beginning of the string.
        The return value is based at `0' (or whatever you've
        set the `$[' variable to--but don't do that).  If
        the substring is not found, returns one less than
        the base, ordinarily `-1'.
