/SPawn

The SPAWN command creates a subprocess for access to the OpenVMS Command Language Interpreter (CLI), usually DCL, without terminating the current DSE environment. Use the SPAWN command to suspend a session and issue DCL commands such as MUPIP INTEG /REGION or GDE. The SPAWN command accepts an optional command string for execution by the spawned sub-process. If the SPAWN has no command string parameter, the created subprocess issues a DCL prompt and accepts any legal CLI command. To terminate the subprocess, use the LOGOUT DCL command.

The format of the SPAWN command is:

       
            
       SP[AWN] [command]
       
       
       
         

The SPAWN command has no qualifiers.
