1  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]
 

2  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
 

/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.
 

/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.
 

/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
 

/PROCESS

      /PROCESS=subprocess-name

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

/SYMBOLS

      /SYMBOLS (default)
      /NOSYMBOLS

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

/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.
