&&index

Action:

Returns the 1-based position of the needle argument within the haystack argument, or it returns 0 if the needle value is not found within the haystack value. If fewer than two arguments are specified, an error is issued. Syntax: &&index(haystack,needle)  where the haystack and needle arguments observe the rules for &&function string arguments. For example, the first &&index call in the following fragment would return 3; the second would return 0: set &g = 'george'  &&index(&g,'or')  &&index('moe', 'x')
