Add keywords and identifiers Add comments Add number literals Add strings Add a lot of new tokens Add (and clean up) IF etc. Improve reporting of unexpected chars / garbage bytes Fix bug with and improved error messages when failing to open file Add verbose-level messages about how files are opened Enforce that files finish with a newline Fix chars returned not being cast to unsigned char (may conflict w/ EOF) Return null path when no file is open, rather than crash Unify and improve error printing slightly Known to be missing: macro expansion, REPT blocks, EQUS expansions
