@everybody, Thanks for all the help!

@#333 I don't think I missed an error but it's certainly possible

Hopefully, this is my final question. When I print my array with printf each string should be printed in a right justifified 20 character column (i.e. the last letter should be indented 20 characters sort of like align left in word.) As per the book's request I created a ruler line to determine how far the last character was actually being indented and it is only being indented 19 characters. I can not figure out why. Any help would be appreciated. Thanks!

#!/usr/bin/perl
use warnings ;
use strict ;
print "This program will display what you type in right justified 20 c
+haracter columns.\nEnter text and press ctrl + d when done.\n" ;
my @userin = <STDIN> ;
print "1234567890" x3 ;
foreach (@userin) {
    printf "%20s", $_ ;
}
