The algorithm for base64 is documented in RFC2045 in section 6... 
specifically, 6.8 I'm not exactly sure what you're asking here.  You say 
that you don't want anyone to write it for you.  Okay, so what DO you 
want?

I explained the algorithm somewhat in the article entitled "RPG and the 
IFS: Text Files in the World" which was published in the January issue of 
iSeries NEWS.  Here's a link to that article on-line (requires a 
ProVIP membership to the iSeries Network):
http://www.iseriesnetwork.com/article.cfm?id=19626

That article also contains a sample of encoding (but not decoding) base64 
code.

There's also an RPG sample of base64 encoding (again, not decoding) in the 
ENCODER4 module of HTTPAPI.

Over the past 10 years or so, I've written five different implementations 
of base64, and 3 of them were for the iSeries.  So, if you have any 
specific questions about the programming part of it, please ask.

But, aside from actually posting my decoding routine (which you 
specifically say you don't want) I don't know how I can help you further?
