Hi BluGeni,

You should prefer the more idiomatic syntax in Eliya’s solution.

Just thought I’d mention that the code snippet you give, which you say “doesn’t seem to do the job,” should actually work fine, except that there’s a semicolon missing after $i=0; in the for loop:

#!/usr/bin/perl
use strict;
use warnings;

my @busi = ( -1, -42, 7, -17 );

for (my $i = 0; $i < @busi; $i++)
{
    $busi[$i] =~ s/-//g;
    print "\$busi[$i] = $busi[$i]\n";
}

__END__

Gives me:

$busi[0] = 1
$busi[1] = 42
$busi[2] = 7
$busi[3] = 17

as required.

HTH,
