>"PL/0 is a programming language, intended as an educational programming language, that is similar to but much simpler than Pascal, a general-purpose programming language. It serves as an example of how to construct a compiler." One potential source code version of PL/0: http://pascal.hansotten.com/niklaus-wirth/pl0/ http://pascal.hansotten.com/niklaus-wirth/pl0/ Two comments: 1) Look at how small the EBNF is (on the Wikipedia page). 2) Look at how small the actual compiler source is (on the second link, above).
