Scheme Programming Language Help

Top-Down Parser Scheme

Need to write the procedures to interpret the rules, handle the errors, and provide a case for eof in the first rule.

Pictures of given procedures below.

Again, the programming language is Scheme. I use DrRacket for the interpreter/compiler.
