All the pieces were there in the thread. I simply rearranged them...

#!/usr/bin/perl -wT
use strict;

my $bin = ascii2bin('Rolf');
my $ascii = bin2ascii($bin);

print "bin   => $bin\n";
print "ascii => $ascii\n";

sub ascii2bin {
  my $ascii = shift;
  my $bin = join '',  map {sprintf "%08b", ord($_)} split //, $ascii;
  return $bin;
}

sub bin2ascii {
  my $bin = shift;
  my $ascii = join '', map {chr(oct"0b$_")} $bin =~ /(\d{8})/g;
  return $ascii;
}

=OUTPUT
bin   => 01010010011011110110110001100110
ascii => Rolf

Or, as one-liners.....

perl -le 'print join"",map{sprintf"%08b",ord($_)}split//,pop' Rolf
perl -le 'print join"",map{chr(oct"0b$_")}pop=~/(\d{8})/g' 01010010011

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
