State management.  Exit the BASIC interpreter.

 

Remarks

QUIT seems to have originated with the unreleased Commodore LCD (BASIC v3.6).  I believe it would exit the BASIC interpreter and return to the "system browser" (I guess it was a like a PlayStation 2+ or XBox).  In BASIC v7.0, however, it only generates a unique error (see example).

 

Example (C128):

QUIT

?UNIMPLEMENTED COMMAND ERROR
READY.

 

GO 64, MONITOR, SPRDEF 

 

BOOT, RUN, SYS
