Given the case,
my @array = (1,2,3,4);
my $var1 = [EMAIL PROTECTED];
my $var2 = [EMAIL PROTECTED];
What's the difference between $var1 and $var2?
Are they all refered to @array?
Thanks guys.

hello lists,
please see the codes below:
use strict;
use warnings;
my @arr = ();
open HD,"itemid.txt" or die $!;
while(){
chomp;
push @arr,$_;
}
close HD;
print "@arr";
the itemid.txt has 470 lines data,looks like:
1210
1211
1212
1213
1214
1215
1216
1217
1218
1219
1220
1221
1222

Whoops, that is the 64-bit version. This the normal version:
http://downloads.activestate.com/ActivePerl/Windows/5.8/ActivePerl-5.8.8.820-MSWin32-x86-274739.msi
Do I need to pay for it?

hello,lists,
When I said:
die "usage: $0 pub|del";
I got this output:
usage: xxx.pl pub|del at xxx.pl line 20.
Then when I said:
die "usage: $0 pub|del\n";
Only the "\n" was added.The output became:
usage: xxx.pl pub|del
It lost the words of "at xxx.pl line 20.".
Why is this?Thank
