Thanks, that worked. However, this is just a sample code. I tried using bigint in my main program and it gives me a whole slew of new errors. It is a GUI program using Tk and a few Tk modules (Tk::TableMatrix, Tk::Balloon, Tk::Bitmap, and Tk::Pane). I'm guessing that bigint and the Tk modules conflict. These are two separate errors I get when I run it with bigint. The second I get when I comment out the first error.

C:\code>DisplayPipeTracer15.pl -trace out.PipeTracer.xml
'8┬¿├⌐☻♥' isn't numeric at C:/Perl/site/
+lib/Tk/Widget.pm line 205.

Here is my code for the lines the errors point to. First is 387 and the second is 159.

Line 387:

bigint basically turns every number into an object which acts as a number. Limit the scope of bigint using curlies, or create the objects yourself were needed.

#!/usr/bin/perl -w
# File displayPipeTracer2.pl

{
   # Only makes objects from numbers in these curlies
   use bigint;

   my $testString = "          00008008 000000FF 00800000";
   $testString =~ s/\s+//g;
   $testString = Math::BigInt->new("0x$testString");

   my $maskResult = $testString & 0x400000000000000000000000;
   print "Mask Result: $maskResult\n";
}

#!/usr/bin/perl -w
# File displayPipeTracer2.pl

my $testString = "          00008008 000000FF 00800000";
$testString =~ s/\s+//g;
$testString = Math::BigInt->new("0x$testString");

my $mask = Math::BigInt->new('0x400000000000000000000000');

my $maskResult = $testString & $mask;
print "Mask Result: $maskResult\n";
