Program Title: VANILLA SNOBOL4 version 2.14
PC-SIG version 1.3
VANILLA SNOBOL4 is an easy-to-learn, flexible language used primarily for
non-numeric applications, such as artificial intelligence, analyzing
databases, text formatting, data conversion, finding patterns in all kinds
of data, searching text files, etc. The language also has a full array of
mathematical functions.
This version of SNOBOL4 does not have real numbers, and the object program
and data cannot exceed 30K in size. Otherwise, VANILLA SNOBOL4 provides
the entire SNOBOL4 programming language as described in textbooks.
VANILLA SNOBOL4 is being used for teaching in college computer science and
humanities departments. A 150-page language tutorial and reference manual
is included on this disk. Source programs for SNOBOL4 are typically five
to ten times smaller than equivalent C or Pascal programs.
Usage: Programming Language.
Google "vanilla snobol" brings up some links to get various versions of
