    longDescription = ''

      "Commodore BASIC" (cbmbasic) is a 100% compatible version of Commodore's

      version of Microsoft BASIC 6502 as found on the Commodore 64. You can use

      it in interactive mode or pass a BASIC file as a command line parameter.

      This source does not emulate 6502 code; all code is completely native. On

      a 1 GHz CPU you get about 1000x speed compared to a 1 MHz 6502.
