What is "snostorm"

Snostorm (Snostorm3) is a version of the SNOBOL4 language with structured programming constructs added. It compensates for the near absence of structured programming constructs in SNOBOL4 by providing IF, ELSEIF, ELSE, LOOP, CASE, and PROCEDURE statements, among others. It was originally designed and implemented by Fred G. Swartz as a preprocessor for SPITBOL running under the Michigan Terminal System (MTS) at the University of Michigan Computing Center during the 1970s.
