1  SPAWN
   Creates a subprocess of the process currently running SDA,
   copying the context of the current process to the subprocess and,
   optionally, executing a specified command within the subprocess.

   Format

     SPAWN  [/qualifier[,...]] [command]
 

2  Parameter
 

command

   Name of the command that you want the subprocess to execute.
 

2  Qualifiers
 

/INPUT

      /INPUT=filespec

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

/NOLOGICAL_NAMES

   Specifies that the logical names of the parent process are not
   to be copied to the subprocess. The default behavior is that the
   logical names of the parent process are copied to the subprocess.
 

/NOSYMBOLS

   Specifies that the DCL global and local symbols of the parent
   process are not to be passed to the subprocess. The default
   behavior is that these symbols are passed to the subprocess.
 

/NOTIFY

   Specifies that a message is to be broadcast to SYS$OUTPUT when
   the subprocess either completes processing or aborts. The default
   behavior is that such a message is not sent to SYS$OUTPUT.
 

/NOWAIT

   Specifies that the system is not to wait until the subprocess
   is completed before allowing more commands to be entered. This
   qualifier allows you to input new SDA commands while the spawned
   subprocess is running. If you specify /NOWAIT, use /OUTPUT to
   direct the output of the subprocess to a file to prevent more
   than one process from simultaneously using your terminal.

   The default behavior is that the system waits until the
   subprocess is completed before allowing more SDA commands to
   be entered.
 

/OUTPUT

      /OUTPUT=filespec

   Specifies an output file to which the results of the SPAWN
   operation are written. To prevent output from the spawned
   subprocess from being displayed while you are specifying new
   commands, specify an output other than SYS$OUTPUT whenever you
   specify /NOWAIT. If you omit the /OUTPUT qualifier, output is
   written to the current SYS$OUTPUT device.
 

/PROCESS

      /PROCESS=process-name

   Specifies the name of the subprocess to be created. The default
   name of the subprocess is USERNAME_n, where USERNAME is the
   user name of the parent process. The variable n represents the
   subprocess number.
