This program is provided AS IS without any support or warranty, expressed or

Vanilla SNOBOL4 was released because we believe many people would enjoy
programming in SNOBOL4, if there was a version of the language that was widely
and freely available. Contributions are NOT requested. Enjoy and share it!
If you become a SNOBOL4 fan, you'll want SNOBOL4+, our $95 professional
version. It allows programs and data up to 300K, assembly-language functions,
real numbers, and has dozens of extensions like: binary and random-access I/O,
include files, built-in Shell sort, Spitbol operators, SAVE files and royalty-
free runtime, dozens of new functions and keywords and a symbolic debugger.
SNOBOL4+ includes a 240-page printed and indexed manual, and over 70 files
of sample programs and functions.
SNOBOL4+ owners also get telephone and written support, and receive "A SNOBOL's
Chance," our relevant and irreverent newsletter.
We also carry all SNOBOL4 books in print, from beginner to advanced, as well
as textual materials -- see file SNOBOL4.DOC for more information.
Enjoy this taste of SNOBOL4, the standard for text manipulation, pattern-
matching, and fun programming. We hope you develop an appetite.
