Terminates processing of the  current  command  procedure.   If  the
  command   procedure   was   executed  from  within  another  command
  procedure, control returns to the calling procedure.

  If a command procedure is  not  being  executed,  the  EXIT  command
  terminates the current image.

  Format:


    EXIT  [status-code]

ParametersExamples

 status-code

  Defines a numeric value for the reserved global symbol $STATUS.  You
  can   specify  the  status-code  as  an  integer  or  an  expression
  equivalent to an integer value.  The value can be tested by the next
  outer  command  level.   The  low-order  three  bits of the longword
  integer value  change  the  value  of  the  reserved  global  symbol
  $SEVERITY.

  If you specify a status-code, DCL  will  interpret  the  code  as  a
  condition  code.   Note  that  even  numeric values produce warning,
  error, and fatal error messages, and that odd numeric values produce
  either no message or a success or informational message.

  If you do not specify a status-code, the current value of $STATUS is
  saved.   When  control  returns  to the outer command level, $STATUS
  contains the  status  of  the  most  recently  executed  command  or
  program.

  1.   $ ON WARNING THEN EXIT
       $ FORTRAN 'P1'
       $ LINK 'P1'
       $ RUN 'P1'

  The EXIT command is used as  the  target  of  an  ON  command;  this
  statement ensures that the command procedure terminates whenever any
  warnings or errors are issued by any command in the procedure.

  The procedure exits with the status value of the command or  program
  that caused the termination.

  2.   $ IF P1. EQS. "" THEN -
            INQUIRE P1 "Enter file-spec (null to exit)"
       $ IF P1 .EQS. "" THEN EXIT
       $ PRINT 'P1'/AFTER=20:00/COPIES=50/FORMS=6

  This command procedure tests whether a parameter was passed  to  it;
  if  the  parameter  was  not  passed,  the procedure prompts for the
  required parameter.  Then it retests the parameter P1.   If  a  null
  string,  indicated  by a carriage return for a line with no data, is
  entered, the procedure exits.   Otherwise,  it  executes  the  PRINT
  command with the current value of P1 as the input parameter.

  3.   $ RUN MYPROG
       ^Y
       $ EXIT

  The RUN command initiates execution of the image  MYPROG.EXE.   Then
  the  CTRL/Y interrupts the execution.  The EXIT command that follows
  calls any exit handlers declared by  the  image  before  terminating
  MYPROG.EXE.
