          o The process is your current process

          o The process is not part of your current job

   terminal control will be switched.

   If you  specify  /IDENTIFICATION  you  cannot  specify  /PARENT  or

   /PARENT

   This is only valid if issued from a sub-process.  It specifies that
   you want to attach to your parent process.

   /IDENTIFICATION.
