    It isn't clear in your original post whether by "Visual" Fortran you
    meant: a GUI IDE for a FORTRAN compiler; a design tool for writing GUI
    interfaces in FORTRAN; or a compiler/toolkit that would let you write
    FORTRAN libraries to be used with GUI applications. In fact, your second
    post makes it sound a bit like you're after not just crewating GUI
    applications, but GUI apps that do elaborate graphics - OpenGL, 3D kinda
    visualisations.

    So, this is not meant as a flame but ... if you ask vague questions,
    where you put a lot more effort into making snide comments about your
    target platform ("Windoze") than into explainly what you're looking for,
    you're probably going to get off-target, unsatisfying answers even from
    folks that are trying to be helpful.

    The Watcom compiler produces binaries that run in the Win32 subsystem of
    Windows NT/2000/XP (as well as DOS, OS/2 and Win16 targets). These
    binaries may have character-mode interfaces, if they have a user
    interface at all. But they are still Win32 binaries. As I recall (haven't
    used Watcom for a couple of years now) there were facilities for creatign
    a Windows GUI for your application, using either FORTRAN or the C++ bits.
    However Watcom is far from being the best choice of tool if you are
    interested in creating complex graphical interfaces and output.

    I assume we're talking about Windows NT, including Windows 2000, XP and
    2003? Every process has a 2GB virtual address space. If it's backed by
    RAM, that's nice. But you can increase the address space by using the
    /3GB switch in teh Boot.INI file, and compiling your app to be 3GB-aware;
    you can also use PAE to address up to 32GB of memory, depending on the
    exact version of Windows you have. Memory above 4GB can't hold executable
    code but I guess you are using memory to hold large amounts of data.

    I could say lots more but it's still hard to work out what you're really
    asking for, sorry. If you can explain your requirements in more detail we
    might be able to give you better pointers.
