VMS Help UIL, Compile Time Errors, ARG_TYPE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  ERROR:   The  declaration  of  the  marked  procedure  specified   a
  different  type  of  argument  than  is  present  in  this procedure
  reference.

  USER ACTION:  Check that you are passing the correct argument to the
  correct  function.  If you intend to call the procedure with varying
  argument types, declare the procedure specifying ANY for the type of
  the argument.
