Re^4: Search Engine Output needs sorting

Reply didn't work... Does ^# give first index? Don't know why you'd need, but curious.

Interesting piece of lateral thinking but, no! By default, array subscripts are zero based in Perl so the first index is `0` and first element is `$array[ 0 ]`. You could change that behaviour by altering a Perl built-in variable but its side effects can be unexpected and its use is deprecated so you really don't want to go there and I won't even tell you which variable it is :-) Cheers, JohnGG	[reply] [d/l] [select]
