EXIT -- Exit from a loop.
usage:  EXIT


FORMAT

  EXIT


  EXIT  terminates  the  flow of control in a Shell loop construct (FOR, SELECT,
  and WHILE).  When EXIT is encountered, control passes  to  the  first  command
  following the body of the loop (see example below).

  You  may also interrupt the flow of control in a loop without actually leaving
  the loop by using the NEXT command.  Type HELP NEXT for more information.

  Do not confuse this command with the DM command EX, which  exits  the  Display
  Manger  and  returns  control  to  the  Boot  Shell.    Type  HELP EX for more
  information.

  The EXIT command requires no arguments or options.


EXAMPLES

  Consider the following section from a Shell script:

     WHILE ((true))
     DO    READC a
           IF ((^a = "y")) THEN EXIT ENDIF
           ARGS "still looking ..."
     ENDDO
     ARGS "Finished."

  When the READC (READ_CHARACTER) command reads a character  into  variable  "a"
  that  matches  the  character  "y",  the  EXIT command executes and causes the
  script to jump to the command following the ENDDO.

  For more information on variables, refer to the DOMAIN System User's Guide.
