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 [[working_with_macro_functions.html#string_functions|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')
