The semantics of a mini language

The language specified here is based on the language accepted by the Basic Evaluator presented in Chapter 1 of Programming Languages - An Interpreter-Based Approach by Samual Kamin. The following files are of interest:

• An example program.
• The syntax specification, along with directives for building the Abstract Syntax Tree.
• The classes corresponding to tokens: integer and identifier
• The classes corresponding to semantic objects: function and variable and scope.
• The class providing a lazy evaluator.
• Supporting modules: debug and global.
