This directory contains the documentation files for Macro SPITBOL.
These documents rarely change.
The SNOBOL4 Programming Language by R. E. Griswold, J. F. Poage and I. P. Polonski.
This is the classic "Green Book" (because of the cover of its color). It is a marvel of typography, and first introduced the use of "beads" to explain SNOBOL pattern matching.
MACRO SPITBOL: The High-Performance SNOBOL4 Language by Mark Emmer and Edward Quillen.
The SPITBOL project notes with sadness the death of Ed Quillen in June, 2012. To quote from Mark Emmer's Acknowledgments in the SPITBOL Manual:
Ed Quillen, local novelist, political columnist, and SNOBOL enthusiast, co- authored this manual. He combined various terse SPITBOL documents from other systems with Catspaw's SNOBOL4+ manual, while providing more complete explanations of some concepts. Any observed clarity is this manual is due to Ed, while the more opaque portions can be blamed on me.
You can learn more about Ed at Ed's web site and [ Denver Post columnist Ed Quillen dies at age 61 in his Salida home](http://www.denverpost.com/obituaries/ci_20781716/denver-post-columnist- ed-quillen-dies-at-age).
v37.min is the source file for SPITBOL v3.7. It is the state of SPITBOL as of 2009 when
Dave Shields took over the maintainer role. The actual code in the current system is
very close to v3.7. The main difference is that the change history has been deleted, and
the MINIMAL specification formerly in this document can now be found in the file minimal.md
The supplied version of v37.min is just the source for SPITBOL converted from all upper case to all lower case.
minimal.md contains the specification of the MINIMAL language, based on the text in v37.min.
SPITBOL is licensed using the GPLv2 (or later) license.
COPYING contains a copy of the GPLv2 license.
COPYING-SAVE-FILE describes licensing issues for a SPITBOL "save file."
COPYING-LOAD-MODULES describes licensing issues for a SPITBOL "load module."
