Please read Writeup formatting tips. Particularly, please wrap your code samples in 'code tags' thus:

<code>
## Your code goes here

Your example will then display as:

#!/fs/COTS/gnu/bin/AIX/perl 

$raw = pack 'H*', '00000034000031b110191403b8811bb1366e4'; 
print for reverse unpack 'dCCVV', reverse $raw

Now, the reason you are not getting the same results is because no linefeeds are being produced, so all the numbers are being abutted. There are three ways to fix that problem.

1. Append the newline character to the end of each thing printed:

   #!/fs/COTS/gnu/bin/AIX/perl 
   
   $raw = pack 'H*', '00000034000031b110191403b8811bb1366e4'; 
   print $_, "\n" for reverse unpack 'dCCVV', reverse $raw

2. Add -l to the shebang line: (This is what I did.)

   #!/fs/COTS/gnu/bin/AIX/perl -l
   
   $raw = pack 'H*', '00000034000031b110191403b8811bb1366e4'; 
   print for reverse unpack 'dCCVV', reverse $raw
   [download]

3. If you are using perl 5.10, then use say instead of print:

   #!/fs/COTS/gnu/bin/AIX/perl 
   
   $raw = pack 'H*', '00000034000031b110191403b8811bb1366e4'; 
   say for reverse unpack 'dCCVV', reverse $raw

BTW: Stupid as it is, some people will get upset with you if you continue to write "PERL". You should use 'Perl' or 'perl' (the first to indicate the language, the second to indicate the interpreter (load module)) in order to avoid that.
