How to compile a program in Befunge-93?

Question

How do I save and compile a program in Befunge-93? What file extension do I need to save the file as (like fileName.what)? Then how do I compile it?

Answer 1

Befunge is typically an interpreted language. In fact it was designed to be difficult to compile because the programs are self-modifying (but that hasn't stopped people from trying to write a compiler).

You should save the file however you like (a .bf extension is typically used) and run the interpreter (bef), passing the filename as a command line argument.

You can see the usage instructions in the source code for the interpreter.
