I'd say that you could adapt PicForth for the PIC18Fxxx in a
reasonable amount of time if you keep the same internal
logic. However, if you want to take the full benefits of the PIC18Fxxx
instruction set, you will have to rewrite parts of the code generator
as there are new conditional and jump instructions that may lead to
smaller and faster code.
