Creates a subprocess, enabling you to execute DCL commands without
   terminating your LATCP session. The LATCP SPAWN command is similar
   to the DCL SPAWN command.

   To return to your LATCP session, either logout of the subprocess
   by entering the DCL LOGOUT command, or use the DCL ATTACH command
   to attach your terminal to the process running LATCP.

ParameterExample

DCL-command
   Specifies a DCL command. If you specify a DCL command, LATCP
   executes the command in a subprocess. Control returns to LATCP
   when the DCL command terminates.

   If you do not specify a DCL command, LATCP creates a subprocess
   and you can then enter DCL commands. You can continue your LATCP
   session by logging out of the spawned subprocess or by attaching
   to the parent process with the DCL ATTACH command.

   LATCP> SPAWN
   $

     The SPAWN command in this example creates a subprocess at DCL
     level. You can now enter DCL commands. Log out or enter the DCL
     ATTACH command to return to the LATCP prompt.
