Specifies  the  module-ident  to  be  used  in  object  file  or
  environment  file  as  needed.   This qualifier is equivalent to
  specifying an explicit [IDENT(quoted-string)] attribute  in  the
  source  file.   An  explicit  IDENT attribute in the source file
  will override this qualifier.  /IDENT=ABC will  yield  an  ident
  string of ABC.  /IDENT="abc" will yield an ident string of abc.
