Brian's choice to use C is perfectly well justified: "I am thinking that we should choose C to implement our PL/0 compiler. Eventually we will want to have this compiler run on many different platforms, including Unix, MS-DOS, and potentially even CP/M. C is a language that will run on every platform I would want to run our PL/0 compiler on, so C works for me. C also requires no special setup so our usual development platform of vim on OpenBSD will work just fine. Finally, it will help with bootstrapping the self-hosting version of the PL/0 compiler, since we in theory could natively compile the C implementation on our target platform then use that to compile the PL/0 implementation, also on the target platform." The reader may learn something from these posts whether they choose to write a compiler in C or not.
