Hi - are there particular advantages to your version that the existing one does not have? For instance, would it improve execution speed substantially? (I would guess this is unlikely - I'm waiting for the Fortran implementation.) Would it make the interpreter more portable? Would it help allow J to be more integrated into conventional environments?
If it's mainly an exercise to improve your lexing and parsing skills, that's fine too. As another poster suggested, you should have fun with it.
