was put there when the Fortran compiler was installed.  I can compile, 
link and run ordinary Fortran programs.   However, I forced the 
installation of CXML and tried to compile one of the examples and that 
failed - couldn't find INCLUDE 'CXMLDEF.FOR'.

I found this on the net and shows CXML installed in a different version 
of OpenVMS -

The system is a Digital Personal Workstation 500au:

and what I see is that there is a FORTRAN, FORRTL and CXML product 
installed.  I can't seem to find anything about the FORRTL product.
