[Below is the C source-code for XXENCODE, an encoding program
that changes a file into characters able to survive transmission
across a network and through various operating systems. It is similar
to UUENCODE but uses a superior character set. Files thus encoded must
be decoded with XXDECODE. Both programs are in the public domain.
Notice that under VM/CMS, these require the Waterloo C compiler. Under
MS-Dos they require the Microsoft C compiler. The usual cc command works
under Ultrix.
XXENCODE has been supplied by Mr. David J. Camp,
david%wubios@wucfua.wustl. ]

[A complete version of this file is now available on
the file-server, s.v. XXENCODE SOURCE. A copy may be obtained
by issuing the command -- GET filename filetype HUMANIST -- either
interactively or as a batch-job, addressed to ListServ@UToronto and
*not* to Humanist. Thus on a VM/CMS system, you say interactively:
TELL LISTSERV AT UTORONTO GET filename filetype HUMANIST; to submit
a batch-job, send mail to ListServ@UToronto with the GET command as
the first and only line. For more details see your "Guide to Humanist".
Problems should be reported to David Sitman, A79@TAUNIVM, after you
have consulted the Guide and tried all appropriate alternatives.]

May I make a plea that HUMANISTS familiarize themselves with the
XXencode/XXdecode programs? [Editor's note: see the above two
messages.] These are completely analagous to the UUencode/decode pair,
in that they translate a binary file (chars > 127) into a plain text
file (all chars <128, all lines shorter than 75 chars), and back again.
Where XXencoding scores over UUencoding is that XXencoding uses
only alphabetic characters and digits. UUencode uses the tilde,
caret, percent, and several other signs. Bitnet is notorious for
muddling these characters up, and if you get a two-to-one conversion,
you can't mend it.
Since HUMANIST is condemned to using Bitnet, we ought to agree
to use XXencode for file exchange, since it really does survive
the worst that Bitnet can do.
For those without a C compiler, I would be perfectly willing to
send in the DOS executables, but of course I would have to UUencode
them! So they might not survive the journey to Toronto and on to you.
