$test corresponds to the individual array item, so you can't exactly just go performing commands on it. Best to use a different variable like this:<br><br>foreach $test (@test) {<br> $testPrint = $test + "n";<br> print $testPrint;<br>}<br><br>Or for this example alone, just do this:<br><br>print $test + "n";<br><br>Best of luck! <p>Liam Morley<br><a href=mailto:lmorley@wpi.edu>lmorley@wpi.edu</a><br><a href=] :: imotic :: website :: [</a><br>"light the deep, and bring silence to the world.<br>

light the world, and bring depth to the silence.
Additionally,<br>the '+' is an arithmatic operator. When you add alphas you get zero.<br><br>If you want to concatentate your elements you need to use '.' or 'join'.<br><br>A simple example......<br><FONT FACE=monospace>#!/usr/local/bin/perl<br>@test = ('bob','sue','joe','ann');<br>$added = $test[0] + "n";<br>print "Added -> $added\n"; <font color=red># prints 0</font><br>$firstTwo = $test[0].$test[1];<br>print "$firstTwo\n";<font color=red># prints bobsue<br></font><br><br>Hope this helps... <p> <br><a href=mailto: > </a><br><a href= > </a><br> keep the rudder amid ship and beware the odd typo
