Allows the user to  execute  DCL  commands  without  leaving  the
     debugger.   If  the  DCL command is specified as the parameter to
     SPAWN, then the command is done within the context of a "spawned"
     subprocess.  For example, "SPAWN MAIL" will put you directly into
     MAIL, and when you exit from MAIL you will be back in DEBUG.   If
     no  parameter  is given to SPAWN, you will receive the DCL dollar
     sign prompt, and you can enter  commands.   Logging  out  of  the
     spawned subprocess will put you back into the debugger.

 Format:

     SPAWN

     SPAWN dcl-command

     SPAWN "dcl-command"

 dcl-command

     Can be any dcl-command.  If the  command  contains  a  semicolon,
     then  the entire command must be placed inside quotes so that the
     debugger doesn't interpret the semicolon as the end  of  a  DEBUG
     command.

     DBG> SPAWN MAIL
     You have 2 new messages
     MAIL> ...

Additional information available:

/NOWAIT/WAIT

     Specifies that the parent process continue in parallel  with  the
     spawned subprocess.  This is the same as SPAWN/NOWAIT in DCL.

     Specifies that the parent process should be  suspended  and  that
     the terminal should be attached to the sub-process.
