I have fuddled with this trying to figure out exactly what is happening but I am at a loss.

UPDATED QUESTION

I orignally thought that if I could understand the script I could rewrite it as a sub that I could pass my $buffer and get back a hex representation and the actual result that I could write back into the file BUT my attempts have failed. Could someone lend me a hand, give me some tips, grant a miracle(make me perl omniscient :) ). thanks again for your time.

In reply to please explain this script by arcnon
