Every line that has $1 on it gives me a "use of uninitialized value in concantination" error that I can't seem to get rid of. i'm writing a script that creates logical drives after detecting a hard disk drive's capacity.

here's my loop:

!c:/Perl/bin/perl.exe -w
use strict ;
use warnings ;
use English ; # required to use long variable names
use vars

if ( /^ArraySize (.+)/ )
   {
   print "\nArray: " . $1 . " yields a LUN of " . int($1/$luns_per_arr
+ay) . "GB\n" ;
   $logical_size = int($1/2);
   if ( ( $logical_size * $luns_per_array ) == $1 ) {$logical_size--;}
   }
