A Winter Study in SNOBOL

Abstract

As a SIP project, I chose to work on an implementation of SNOBOL4 for the VAX 11/750. Since SNOBOL4 is an interpretive language, I first wrote Pascal procedures to translate SNOBOL4 source code into Pascal linked list data structures. The next step was to write procedures which would interpret the Pascal structures and emulate SNOBOL4 code. Although I have diagrammed many flowcharts for the interpreter procedures, the procedures themselves have not yet been implemented.
