This is a compiler for PL/0. This was written for a university course on introductory compiler design. It compiles to a pseudo assembly language called p-code. The executable also includes an interpreter for p-code.

As input, the program takes a PL/0 program. It compiles it into p-code, then executes it. There are several flags for runtime stack-tracing and showing scanner/parser intermmediate output. Use ./plrun -h to see what they are.

1. Run make. This will create the plrun executable in the root directory

2. To run the PL/0 Compiler/VM, type the following, substituting the names for the input and output files.

   ./plrun -i input_file -o output_file

Some example programs are available in the test/ directory.

The program has only been tested on 64 bit Ubuntu 12.10 Linux. It only uses standard libraries, so it should compile on just about anything.
