I'm sure this is going to be really basic, but I've gone several decades using Perl and never needed the pack or unpack functions before.

#!/usr/bin/perl
use strict;
use warnings;
#
my $pReqsca = "ABCD";
my @bytary = unpack 'C*', $pReqsca;                                   
+      
my $binstr = '';                                                      
+      
foreach my $scabyt (@bytary) {                                        
+      
    my $intbyt = int($scabyt);                                        
+      
    my $hexbyt = sprintf("%02X", $intbyt);                            
+      
    my $binbyt = unpack 'b8', $scabyt;                                
+      
    $binstr .= $binbyt;                                               
+      
    print "  Byte = [$scabyt]  Integer = [$intbyt]  Hex = [$hexbyt]  B
+inary = [$binbyt]  Binary String = [$binstr]\n";
    print "Aborting Loop\n";
    last;
}

Results:

W:\Steve\PerlMonks>perl sopw-584100.pl
  Byte = [65]  Integer = [65]  Hex = [41]  Binary = [01101100]  Binary
+ String = [01101100]
Aborting Loop

Same results using 'B8',
Last time I checked, Hex 41 should show binary 01000001.

What am I missing here?
