Here's the code: 
sub file_processing {
$script = "/export/home/ssesar/Perl/another_script.pl -e";
$open = "$script $arg1 $file1";
open(FILE1, "$open |") or die "can't do it\n";
      while (<FILE1>) { 
          chomp;
 next if /^\#/;
        next if /None/;
        next if /Unkno/;
        next if /unkno/;
        next if /NONE/;
          @_ = split ( /\n/, $_);
          @array1 = @_;
      }
close FILE1;

}

I'd like to know if I could replace: 
$open = "$script $arg1 $file1";
open(FILE1, "$open |") or die "can't do it\n";

[download]
with: 
$open = "$script $arg2 $file2";
open(FILE2, "$open |") or die "can't do it\n";

[download]
and: 
@array1 = @_;

[download]
with: 
@array2 = @_;

...within the same subroutine. Not a whole lot to re-type, if I needed to create 2 different subroutines, but I'd like to learn to program as efficiently as possible.
