Hi there, I'm reading the variable $selectcriterium, either being '<' or '==' and then want to use them for a selection between two other variables also read in. Surely it must be possible to write the following code more effectively and shorter. I just failed to find the way. Can you advise me, please. Thanks, Gerd 

#!/usr/bin/perl
#These are the variables to be read in
my $number1 = '2011';
my $number2 = '2011';
my $selectioncriterium = '==';

#This is the algorithm
if  ($selectioncriterium eq '<')
    {
        if ($number1 < $number2)
            {
                print "$number1 is smaller than $number2\n";
            }
        elsif ($number2 < $number1)
            {
                print "$number2 is smaller than $number1\n";
            }
    }
    elsif ($selectioncriterium eq '==')
        {
            if ($number1 == $number2)
                {            
                    print "$number1 is equal to $number2\n";
                }
                else
                    {
                        print "$number1 is not equal to $number2\n";
                    }
        }
