Ravelli released a new version of Forth for the Commodore C64. Forth is a very low-level and minimal language without any automatic memory management. Forth on the C64 is more faster, more memory effective and more powerful than the standard Basic. Forth on the C64 includes an editor, compiler and a assembler. Changes in this version: Optimizations for the parameter stack, "ls" and "branch". And added "depth", "sp0" and "sp1".
