XPLNCODE.PM for XyWrite 3+ | XyWrite 4 | Nota Bene for DOS
C.L.Distefano rev.2017-11-29

XPL encoding, originally developed by Robert J. Holmgren, is a reliable
method for transmitting XyWrite Programming Language (XPL) code safely
over the internet, in human-readable form. It is the traditional way to
include XPL code in the body of email messages posted to the XyWrite
Mailing List, <http://www.freelists.org/list/xywrite>.

XPLNCODE.PM makes this encoding|decoding method available to users of
all versions of XyWrite and Nota Bene for DOS, as well as for users of
Nota Bene for Windows.

Required External Files
-----------------------
Two 32-bit Windows binary files, XPLENC.EXE and XPLDEC.EXE, must be
present in the directory that XyWrite|Nota Bene uses to write temp files
(<VADR>). These files are included in XPLENC.ZIP, available at:
http://xywwweb.ammaze.net/dls/XPLENC.ZIP
