Allows the specific name of an intrinsic procedure to be used as an
  actual argument.  (Not all specific names can be used as actual
  arguments.  For more information, see the HP Fortran for OpenVMS
  Language Reference Manual.)

  The INTRINSIC attribute can be specified in a type declaration
  statement or an INTRINSIC statement, and takes one of the following
  forms:

  Type Declaration Statement:

   type, [att-ls,] INTRINSIC [,att-ls] :: v[,v]...

  Statement:

   INTRINSIC v [,v]...

     type      Is a data type specifier.

     att-ls    Is an optional list of attribute specifiers.

     v         Is the symbolic name of an intrinsic subprogram.

  Subprogram names passed as actual arguments must be identified in
  INTRINSIC statements.  Names of subprograms used as the objects of
  CALL statements or function references do not need to be identified
  by means of INTRINSIC statements; these names are recognized as
  intrinsic implicitly.

  The INTRINSIC attribute is compatible with the PRIVATE and PUBLIC
  attributes.
