Thanks for the help! However, could you guide me a little bit farther. I have tried to change my code to this: 
open SCRIPT, "otherScript.pl |" or die "script failed: $!";
$resultsBox->insert('end', $SCRIPT);

I am sure that I am not implementing this correctly. I am assuming that I will need to do a loop of some sort to keep inserting the new lines until the script is finished. But, I am at a loss with the new code you gave me. Also, I don't know what you mean by I could use <SCRIPT>. My separate code is line-based and should only pass text. I did put a line in my called script of $| = 1;.
