    1.$ CREATE DOFOR.COM
      $ ON WARNING THEN EXIT
      $ IF P1.EQS."" THEN INQUIRE P1 FILE
      $ FORTRAN/LIST 'P1'
      $ LINK 'P1'
      $ RUN 'P1'
      $ PRINT 'P1'
 <Ctrl/Z>

      $ @DOFOR AVERAGE

      This example shows a command procedure, named DOFOR.COM, that
      executes the FORTRAN, LINK, and RUN commands to compile,
      link, and execute a program. The ON command requests that
      the procedure not continue if any of the commands result in
      warnings or errors.

      When you execute DOFOR.COM, you can pass the file specification
      of the FORTRAN program as the parameter P1. If you do not
      specify a value for P1 when you execute the procedure, the
      INQUIRE command issues a prompting message to the terminal and
      equates what you enter with the symbol P1. In this example,
      the file name AVERAGE is assigned to P1. The file type is not
      included because the commands FORTRAN, LINK, RUN, and PRINT
      provide default file types.

    2.$ @MASTER/OUTPUT=MASTER.LOG

      This command executes a procedure named MASTER.COM; all output
      is written to the file MASTER.LOG.

    3.$ CREATE FILES.COM
      *.FOR, *.OBJ
 <Ctrl/Z>

      $ DIRECTORY @FILES

      This example shows a command procedure, FILES.COM, that
      contains parameters for a DCL command line. The entire file is
      treated by DCL as command input. You can execute this procedure
      after the DIRECTORY command to get a listing of all FORTRAN
      source and object files in your current default directory.

    4.$ CREATE QUALIFIERS.COM
      /DEBUG/SYMBOL_TABLE/MAP/FULL/CROSS_REFERENCE
 <Ctrl/Z>

      $ LINK SYNAPSE@QUALIFIERS

      This example shows a command procedure, QUALIFIERS.COM, that
      contains qualifiers for the LINK command. When you enter the
      LINK command, specify the command procedure immediately after
      the file specification of the file you are linking. Do not type
      a space between the file specification and the @ command.

    5.$ CREATE SUBPROCES.COM
      $ RUN 'P1' -
        /BUFFER_LIMIT=1024 -
        /FILE_LIMIT=4 -
        /PAGE_FILES=256 -
        /QUEUE_LIMIT=2 -
        /SUBPROCESS_LIMIT=2 -
        'P2'  'P3'  'P4'  'P5'  'P6'  'P7'  'P8'
 <Ctrl/Z>

      $ @SUBPROCES  LIBRA  /PROCESS_NAME=LIBRA

      This example shows a command procedure named SUBPROCES.COM.
      This procedure issues the RUN command to create a subprocess to
      execute an image and also contains qualifiers defining quotas
      for subprocess creation. The name of the image to be run is
      passed as the parameter P1. Parameters P2 to P8 can be used to
      specify additional qualifiers.

      In this example, the file name LIBRA is equated to P1; it
      is the name of an image to execute in the subprocess. The
      qualifier /PROCESS_NAME=LIBRA is equated to P2; it is an
      additional qualifier for the RUN command.

    6.$ CREATE EDOC.COM
      $ ASSIGN SYS$COMMAND:  SYS$INPUT
      $ NEXT:
      $      INQUIRE NAME "File name"
      $      IF NAME.EQS."" THEN EXIT
      $      EDIT/TPU 'NAME'.DOC
      $      GOTO NEXT
 <Ctrl/Z>

      $ @EDOC

      This procedure, named EDOC.COM, invokes the EVE editor. When
      an edit session is terminated, the procedure loops to the
      label NEXT. Each time through the loop, the procedure requests
      another file name for the editor and supplies the default
      file type .DOC. When a null line is entered in response to
      the INQUIRE command, the procedure terminates with the EXIT
      command.

      The ASSIGN command changes the equivalence name of SYS$INPUT
      for the duration of the procedure. This change allows the EVE
      editor to read input data from the terminal, rather than from
      the command procedure file (the default input data stream if
      SYS$INPUT had not been changed). When the command procedure
      exits, SYS$INPUT is reassigned to its original value.

    7.! PEOPLE.DAT
      ! A set of data with embedded key qualifiers for the SORT command.
      !
      ! Usage: SORT@PEOPLE.DAT
      !
      /KEY=(POS:10,SIZE:10) sys$input people.out
      Fred     Flintstone    555-1234
      Barney   Rubble        555-2244
      Wilma    Flintstone    555-1234
      Betty    Rubble        555-2244
      George   Slate         555-8911
      Dino     Dinosaur      555-1234
      $!
      $ purge people.out
      $ type people.out

      Creates a sorted list of people in file PEOPLE.OUT and displays
      it. This demonstrates when using "@" in the middle of a DCL
      command, DCL redirects the entire file as command input.
