in reply to Finding target unspecified value

  DB<113> use List::Util qw/max/

  DB<114> @array = map {int (rand(91))+10} 1..5
 => (36, 56, 42, 38, 49)

  DB<115> $max = max @array
 => 56

    Feeling not a neutered dog...just not getting it. I attempted both version of the code posted, and it keeps popping up errors on my screen. Not even sure anymore what the heck am I doing wrong with this.

      Do this to use my idea: 

      ...

# add this line
my $maxval = 0;
foreach (@array) {
    $maxval = $_ if $_ > $maxval; # and populate as needed here
    print $_, "\t";
    $counter ++;
    if ($counter % 4 == 0) {
        print "\n";
    }
}

# then include the value in your final print statement
print "The largest element is: $maxval\n";

      On the other hand, to use max as shown by Rolf do this: 

      use strict;
use List::Utils qw/max/; # add this line

... # rest of your code is unchanged

# and then use the function in your final print statement
print "The largest element is: " . max(@array) ."\n";

      The answer to the question "Can we do this?" is always an emphatic "Yes!" Just give me enough time and money.

        Boftx that solved the riddle for me. I appreciate taking your time with this on me. I feel like when trying to understand Perl I was told to build a house with a whoopee cushion. Also I appreciate others input as well. Hopefully I can get the hang of this so I can be quasi useful to someone else.
