Submit: Turn in your Interpreter.java source file using the turnin command on morbius.mscsnet.mu.edu or one of the other Systems Lab machines.

Work is to be completed individually. Be certain to include your name in the file. You may submit multiple times, but only the last turnin will be kept. The automatic submission system will not accept work after the deadline. (See turnin instructional video HERE. Note that the video is for a different course number, and that Morbius's domain name has changed since the video was made: morbius.mscs.mu.edu-> morbius.mscsnet.mu.edu)

Include a comment block at the very top of each file that contains the following:

/**

 * Explain briefly the functionality of the program.
 * @author [your name]
 * Instructor [your instructor]

Straightline Interpreter

Project 1 is intended to serve as a quick review of Java, and a gentle introduction to the first few concepts in the textbook.

• Read Chapter 1 of Appel.
• Download Java code for "straight-line" language abstract syntax trees, here.
• Download skeleton code for "straight-line" language interpreter, here.
• In working directory, compile the abstract syntax tree classes. (javac StraightLine.java.)
• In Interpreter.java, implement the rest of the interpreter code where indicated by comments, as explained in textbook and in lecture.
• Compile and run interpreter. (javac Interpreter.java; java Interpreter.)
  You will need manually built AST's (abstract syntax trees) stored in a class called Program.
  A couple of example programs are provided here and here.
  You would do well to construct additional testcases.
• Debug until done.
