2  Parameters

process-name

   Specifies the name of a parent process or spawned subprocess to
   which control passes. The process must already exist, be part
   of your current job, and share the same input stream as your
   current process. However, the process cannot be your current process 
   or a subprocess created with the /NOWAIT qualifier.

   Process names can contain from 1 to 15 alphanumeric characters.
   If a connection to the specified process cannot be made, an
   error message is displayed.

   The process-name argument is incompatible with the
   /IDENTIFICATION qualifier.

2  Qualifiers

/IDENTIFICATION 

      /IDENTIFICATION 
      /NOIDENTIFICATION (default)

   Specifies the process identification (PID) of the process to
   which terminal control will be transferred. Leading zeros can
   be omitted. The /IDENTIFICATION qualifier is incompatible with
   the process-name argument.

   If you omit the /IDENTIFICATION qualifier, you must specify a
   process name.
