EFI$HELP.HLB  —  SPAWN
    Creates a subprocess of the current process. The context of
    the subprocess is copied from the current process. You can use
    the SPAWN command to leave EFI$CP temporarily, perform other
    functions (such as reading your mail), and then return to EFI$CP.

    Format

      SPAWN  [command]

1  –  Parameter 

 command

    Specifies the DCL command string that executes in the created
    subprocess. When the command completes, the subprocess terminates
    and control is returned to the parent process. If this parameter
    is not specified, a subprocess is created that transfers control
    to the DCL command level.

2  –  Qualifiers

2.1    /INPUT 

       /INPUT=filespec

    Specifies an input file containing one or more DCL command
    strings to be executed by the spawned subprocess. If you specify
    a command string along with an input file, the command string is
    processed before the commands in the input file. After processing
    is complete, the subprocess is terminated.

2.2    /LOGICAL_NAMES 

       /LOGICAL_NAMES (default)
       /NOLOGICAL_NAMES

    Specifies whether the logical names of the parent process are
    copied to the subprocess. When you do not want the subprocess to
    use the logical names of the parent process, enter the qualifier
    /NOLOGICAL_NAMES.

2.3    /OUTPUT 

       /OUTPUT=filespec

    Identifies the output file to which the results of the SPAWN
    operation are written. If you omit the /OUTPUT qualifier, output
    is written by default to the current SYS$OUTPUT device. Whenever
    you use the /NOWAIT qualifier, you should also use the /OUTPUT
    qualifier to specify a new output destination. Doing so prevents
    output from being displayed on your terminal while you are
    entering

2.4    /PROCESS 

       /PROCESS=subprocess-name

    Specifies the name of the subprocess. The default name of the
    subprocess is USERNAME_n.

2.5    /SYMBOLS 

       /SYMBOLS (default)
       /NOSYMBOLS

    Determines whether the system passes DCL global and local symbols
    to the subprocess. The default is /SYMBOLS.

2.6    /WAIT 

       /WAIT (default)
       /NOWAIT

    Controls whether EFI$CP waits until the subprocess is completed
    before allowing more EFI$CP commands to be entered. The /NOWAIT
    qualifier allows you to enter new EFI$CP commands while the
    specified subprocess is running. If you specify /NOWAIT, you
    should also use the /OUTPUT qualifier to direct the output stream
    to a file rather than to your terminal. Doing so prevents your
    terminal from being used by more than one process simultaneously.
