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.

$!
$ 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.
8.$ CREATE SUBPROCES.COM
$ RUN 'P1' -
/BUFFER_LIMIT=1024 -

<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 P16 can be used to
specify additional qualifiers. This is applicable if bit 3 of
DCL_CTLFAGS is set to 1. 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.
