Re: Re: subtract one array from another

The $#array syntax is vaguely deprecated, IIRC...

for my $search (0..scalar @array1)
[download]

But since the .. operator takes scalar context, you can just say

for my $search (0..@array1)
[download]

(Update: the "vague deprecation" was from one of the Apocalypses. So it's safe for the indefinite future, I suppose. cf. Apocalypse 2)

Don't you need a -1 there someplace? `perl -le ' @a = qw/a b c d/; print scalar @a; print $#a; __DATA__ output: 4 3 '` [download] -- Dan	[reply] [d/l]

Yes I seem to remember hearing that... But then Juerd corrected me. I do not believe that it will in fact be going away. And of course as the someone else mentioned that should be @array1-1 :-) --- demerphq my friends call me, usually because I'm late....	[reply]
