I see, scalar used where list expected.
How about this:
#!/bin/perl
use strict;
use warnings;
use Data::Dumper;
my @keys = qw(fe fi fo thumb);
my @valone = 1..4;
my @valtwo = 10..14;
my %hash;
@[EMAIL PROTECTED] = [EMAIL PROTECTED],@valtwo];
print Dumper(\%hash);
$VAR1 = {
'fo' => undef,
'fi' => undef,
'fe' => [
1,
2,
3,
4,
10,
11,
12,
13,
14
],
'thumb' => undef
};
I can't see why you can't create a slice hows values are arrays or
why all the values are assigned to the first key.
Not a biggy. I can work around it but I'm interested to know.
Thanx,
Dp.
