Re: FAQ: UUDecoding
------------------------------------------------------------------------

UUEncoding/Decoding is a method for representing a series of eight bit
binary characters in a series of six bit equivalents. This is to allow
transmission of all characters without using any characters that might
be considered control characters by the transmission system. You may use
UUEncoding to broadcast binary files over this Fidonet echo, provided
that it isn't too large. In general, if you have to break up the encoded
file over two or more messages, then it's probably too big. In that case
you should make the binary file available for downloading or f'req'ing
from a BBS system. Also the preferred method of transmission over the
echo is assembler source code. If that is impractical, then you may
encode the binary file in a Dos' Debug script format. And finally you
may try UUEncoding, before going to the download/file request path.

Below is a Debug script of a free UUDecoder, written by David
Kirschbaum, so one may decode any UUEncoded scripts that might by
transmitted over this echo:

Re: FAQ: UUEncoding
------------------------------------------------------------------------

Below you will see an example of what an UUEncoded script looks like.
The example below is in fact an UUEncoding of a free UUEncoder program,
written by David Kirschbaum. The complete archive, with executables,
source code, and documentation is available from the author and many
other sites. So after you've captured this message, you may use the free
UUDecoder program from the previous message to decode the script below,
and you will be able to make your own UUEncoded files from now on.

To create the executable from the script, you would run the UUDecoder
from the DOS command line like this:

UUD20 script

Where "script" is filename and extension of the script without the
quotes.

After creating the UUEncoder, you can begin creating UUEncoded files of
your own, you would do this from the command line:

UUE20 source > destination

Where "source" is the filename and extension of whatever you are trying
to encode, while the "destination" is the name of the final encoded
script.

Here's the script of the UUEncoder, to decode simply remove all
descriptive text above the double line:
