The GO keyword does not make a complete statement by itself. It pairs with the TO keyword to form a synonym for GOTO, so you can type GO TO with a space.
In BASIC 7.0, it forms part of the GO64 statement, which switches the Commodore 128 to Commodore 64 mode. The number can be any numeric expression that evaluates to 64, and a space is permitted after the GO.
