Can the new Tc++ gen- I don't think that BC++ (turbo C++ for windows' new name) can generate Weitek code. Instead of going with BC++ or any other 16 bit compiler I would look at '386 (or '486) specific compilers (Zortech's ZC++, Watcom v8 for '386, etc.) I think that you would get better usage out of your CPU (and computer) by using the faster '386 instructions and flat addressing space. I believe that you will see better (i.e. faster) results by using a '386 compiler w/o the Weitek then you would by using a '286 compiler (BC++, Microsoft, etc) and the Weitek chip (even if the 2 '286 compilers I listed supported the Weitek, which they don't). You will also save money - $ for '286 compiler + Weitek > $ for '386 compiler. If you MUST have the Weitek chip I think that there are a few compilers that support it and they are all '386 compilers anyway - MetaWare (not sure about Weitek support), Microway NDP (C and C++, '386 and '486, w/ Weitek support), etc... john gay.
