REBOL 3 Usage: Quitting REBOL

To exit REBOL at any time, select quit from the Console file! menu or by typing quit or q at the prompt.

You can also quit the program from within a script:

if now/time > 12:00 [quit]

The REBOL console may also quit if an error occurs during startup.

Exit Does Not Quit

Do not use the word exit to quit REBOL. This word is used for exiting functions and it will return an error if typed at the console.
