1.3.1 Starting, stopping, and interrupting Yorick

Start Yorick by typing its name to your terminal emulator. When you are done, use the quit function to exit gracefully:

% yorick
  Yorick ready.  For help type 'help'.
 > quit

You can interrupt Yorick at any time by typing Control-C; this causes an immediate runtime error (see section 1.3.7 Error Messages). (Your terminal emulator and operating system must be able to send Yorick a SIGINT signal in order for this to work. On UNIX systems, you can set this character using the intr option of the stty command; Control-C is the usual setting.)
