1296.0. "VISUAL FORTRAN- Status Bit register" by LYOV00::BERNOU () Tue May 13 1997 08:24

    with Fortran from Microsoft, it is not possible to modify the Status bit
    Register when an error occurs, i.e. zero reset.
    
    Is it possible with Visual Fortran ?

In general, it is not a good idea to fiddle with the hardware registers behind the compiler's back. If one wanted to do that, great care would have to be taken, and even then, that fiddling may cause problems with the code generated by the compiler. Could you give us an example of what you're trying to accomplish, and maybe we can propose a supported solution to your problem. Thanks, - Lorri

    In general, it is not a good idea to fiddle with the hardware registers
behind the compiler's back.  If one wanted to do that, great care would have
to be taken, and even then,  that fiddling may cause problems with the code
generated by the compiler.

    Could you give us an example of what you're trying to accomplish, and
maybe we can propose a supported solution to your problem.
