BrainF**k Simulator Download
This contribution by Christine E. Meyer, a student at University of Illinois at Springfield, is a Pep/9 assembly language implementation of the famous esoteric programming language BrainF**k. See here for a description of the language. The simulator runs a compiler that takes input from the source program terminating in a *
sentinel then executes the compiled code. You can paste the following program into the Pep/9 Input pane and run the simulator. The program outputs Hello World!
