/TIE
  /NOTIE  (D)

  Generates code that allows native OpenVMS I64 images to call
  translated Alpha images and translated OpenVMS Alpha images to call
  native OpenVMS I64 images.  This qualifier is supported on
  OpenVMS I64 systems only.

  Specify /TIE when you want to use native, compiled code with
  shared translated Alpha images, either because the code might call
  into a translated Alpha image or because it might be called from a
  translated Alpha image.  If you specify /TIE, you should link the
  object module using the LINK command qualifier /NATIVE_ONLY.
  See the OpenVMS Linker Utility Manual for information about the
  /NATIVE_ONLY qualifier.

  Specifying /NOTIE, the default, indicates that your compiled code
  is not associated with a translated Alpha image.
