 Hi,
Thanks for the reply, i knew you that base 64 had no problem with EBDIC (at 
least this :)), only the c source contanis many questions that are ascii 
dependent (something like  return(((cc >= 33) && (cc <= 60)) || ((cc >= 62) && 
(cc <= 126))) AND  something like this if ((dd == '\n') || (dd == '\r') || (dd 
== '\0')) {;) so we need to prot it carefully this is doable however i tried to 
make it shorter.
Thanks again for your reply

I've written base64 encoders & decoders in RPG IV and Visual Basic.
Unfortunately, I'm not allowed to share this code as I do not own it, it's
owned by the company who paid me to write it.

However, open-source/public-domain base64 utilities (mostly written in C)
are widely available on the Internet. Here's a link to one such utility:
http://www.fourmilab.ch/webtools/base64/

FWIW, base64 works just great in EBCDIC. Unlike uuencode, base64 attempts
to only use invariant characters so that it'll work with any charset. Of
course, if you have an ASCII file that you base64 decode on an EBCDIC
machine, the result will be still be in ASCII -- that's the whole point of
base64, to maintain the exact same binary values when sending a file
through e-mail. If you need it to be EBCDIC, your next step might be
to call the QDCXLATE API. Or simply run it through an an existing tool
like CPYFRMSTMF to convert it.

Good luck!
