OS/2 eh. That's my old stomping ground.

Anyway, if you would post a small sample, encoded using MIME::Base64, along with a description of what you think the sample represents, I'll have a go at it. No guarentee's I'll do any better than you of course.

You can encode the sample using

perl -mMIME::Base64=encode_base64 -000e" print encode_base64( <> )" 
   < sample >sample.b64

and then paste it in a code block here.
