2912.0. "RISC FORTRAN and windows" by CAADC::PMWVESTUTO () Mon Jun 11 1990 13:28

    I need some direction....
    
    My customer currently has a working application based on VAX FORTRAN,
    VMS, and XLIB routines. He is in the process of porting this
    application to RISC, MIPS FORTRAN, and XLIB but he is having major
    difficulties. The first obstacle is the LACK of documentation around
    RISC FORTRAN and XLIB. Does anyone know of ANY documentation that would
    come near to addressing his need?
    
    Next, the customer is willing to pay for help in the actual port. Do we
    have people within Digital who know RISC FORTRAN, and X windows? How
    can we make their knowledge available to the customer?
    
    This customer is an OEM of ours, and once this port is done, it means
    business to DEC. It's obviously in our best interest to help.
    
    The customer is also looking at using our RISC FORTRAN compiler when it
    comes out. But are we providing any docuementation for our compiler and
    XLIB??
    
    Any direction/information would be VERY useful.
    
    Thanks,

Please try to separate in your mind (and in your customers') the issues of the
compiler and the declarations.  It is the responsibility of the producers of
the software being called to document how to call the routines, at least in
a generic fashion.  It is unfortunately true that this isn't done - the
existing DECwindows programmer interface documentation assumes C.

On RISC systems, you will have to use the same routines that C uses - there
are not and won't be separate declarations akin to the "VAX bindings" on VMS and
VAX Ultrix.  The FORTRAN documentation should tell you how to translate
"C-speak" to FORTRAN for the purposes of declaring data structures and calling
the routines.  At the present time, it does not appear that anyone is going
to provide a set of non-C declarations for the standard X11 routines and
structures.

I wish you much luck.  And if you can bend the ear of DECwindows product
management to tell them how important FORTRAN is to your customer, so much
the better.

    Anybody has any sample X-windows code for RISC ?
    My customer needs it ASAP.
    Thanks
