/sys$common/syshlp/helplib.hlb NCS Command, Command Qualifiers, /INSERT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  /INSERT

   Use this qualifier to add one or more definition modules  to  an  NCS
   library. If the input file(s) contains more than one definition, NCS
   creates a separate entry in the library for each.

   Before NCS inserts a definition into an  existing  NCS  library,  it
   verifies that the library  does  not already  contain  a  definition
   module having the same name. If NCS finds a definition  module  with
   the same name, it does not add the  new  definition  module  to  the
   library but it does issue an appropriate error message.
