This message is to Roland and to everyone who will find the
reading interesting. I am posting this message here because
I lost Roland Bitnet/Internet address so I was unable to send
him a direct E-mail. But I think the reading is of general
interest.....so enjoy   :)

Hello!
Sorry for the very delayed response....somehow, I failed to read your mail
before the system marked it as old mail. I was doing some deleting
of my old mails listing, when I bump in to this mail that I couldn't
remember what it was about......anyway, better late than never  :)
 
First of all, about your question in regards to UUENCODEing....
UUENCODE is a program available mostly in Unix system that
allows a binary file (which consist of 8 bits characters) to be
converted to a ASCII (or text) file (which consist of 7 bits characters).
(The difference between 8 bits characters and 7 bits characters
is not in the characters itself, but it is in the range of characters.
By this I mean: An ASCII file contains characters that can be
represented with 7 bits, or from 0 to 127, which are the
alphanumberic characters plus some others; A binary file contains
characters that can be represented with 8 bits, or from 0 to 255,
which are all the characters that can be represented with 7 bits
and more. This is why, if you are able to send electronically
a binary file, you should also be able to send an ASCII file by
the same means, but not vise-versa).
By doing this convertion you can send that file to anyone as any
ordinary E-mail through the Mail system, or you can post it
to the newgroupp. You can't do that with a binary file as it is
because 8 bit characters consist of characters that can't be
printed or represent screen commands; moreover, the mail
system can only send 7 bit data.
Once you receive a uuencoded file you must UUDECODE the file
before you are able to use the file.
 
 
Sincerely,
Scott K. Stephen
 
 
P.S.  Roland, if you read this post, please send me a E-mail
      with your bitnet or internet address. Thanks.
