SPITBOL 360 was the first true compiler for SNOBOL4 and is an incredibly clever work of assembly language. SPITBOL 360 was originally distributed under license, for a fee, from 1971 until 1984 when it was superseded by SPITBOL 370.The General Public License (GPL) version 2, June 1991 is available at http://www.gnu.org/licenses/gpl-2.0.html.
Thanks to Robert Dewar and Ken Belcher for allowing me [Mark B. Emmer] to re-release SPITBOL 360 under the GPL for all to use and study.
