Commodore 64 Commands, Functions, And Reserved Words:

NOTE: The command set of the C64 is less refined and advanced than the one
for the Apple II. Almost every command the C64 has is also available on the
Apple II (with a few exceptions), while the Apple II has several specific
commands which the C64 doesn't. Therefore, the C64 keywords here are not
elaborated upon, as they mostly duplicate the Apple II's functionality.
