VMS Help DTM, REVIEW, Review Subsystem, ATTACH, Command Qualifiers  *Conan The Librarian (sorry for the slow response - running on an old VAX)

1 - /IDENTIFICATION

   /IDENTIFICATION=pid

   Specifies the process identification (PID) of the process to which
   you want to attach the terminal. You can omit the leading zeros
   when you specify a PID.

   If you specify the /IDENTIFICATION qualifier, do not specify the
   process name parameter or the /PARENT qualifier. If you do not
   specify a qualifier, you must specify a process name.

2 - /PARENT

   Specifies that the process you want to attach to is the original
   (parent) process.

   If you specify the /PARENT qualifier, do not specify the process
   name parameter or the /IDENTIFICATION qualifier. If you do not
   specify a qualifier, you must specify a process name.
