Use EXIT to terminate a repetitive prompt such as NEW>, OLD>,  or
 ECO>,  or  to  terminate a PATCH session and pass control back to
 the  command  interpreter.   You  can  also  specify  CTRL/Z   to
 terminate a PATCH session.  Issue CTRL/Z in response to the PATCH
 prompt (PATCH>).

 Do not type EXIT in response to the value prompt (VAL>)  for  the
 DEFINE  command.   For  this command, only the name prompt (NAM>)
 recognizes the EXIT command.

 Format:

      EXIT
