Projects
Simple Interpreter with
an Interactive Debugger
Allen Benton created a sample project that implements an interpreter for the the 'Simple' programming language. This project contains a number of debugger abilities which include:
  1. Step Trace highlights the currently active step and prints debug messages
  2. Single Step highlights the currently active step and pauses after each step execution
  3. Step Delay defines the wait time between steps.
