Hello,

I am trying to pass an array by reference since it could become very large. The function should take the array and print it out but only 10 elements per line.


#!/usr/bin/perl -w

use strict;
use warnings;

use DBI;

......

sub printlist
{

        my $arrayref = @_;
        my $max = $arrayref;
        my $nmax;
        for(my $i = 0; $i <= $max; $i++) {
                print "\t\t\t\t\t";

                if ( ($max - $i) >= 10 ) {
                        $nmax = 10;
                } else {
                        $nmax = $max - $i;
                }

                for(my $n = 0; $n <= $nmax; $n++) {
                        print "$arrayref->[$i]\t";
# line 209              $n++;
                        $i++;
                }
                print "\n";
        }

}

......

&printlist([EMAIL PROTECTED]);

But I am receiving the following error:
Can't use string ("1") as an ARRAY ref while "strict refs" in use at ./mysql-watch.pl line 209.



Does anybody know why ?

Thanks

Michael
