Witherspoon) Newsgroups: comp.lang.c++ Subject: C++ without an O/S Keywords: To DOS or not to DOS Message-ID: <370@fenix.Atlanta.NCR.COM> Date: 10 Aug 88 15:20:47 GMT Organization: NCR Systems Engineering - Retail / Atlanta Lines: 28 Here we sit, ready to complete an object-oriented design for a multiple-display package. What we need is a platform on which to run our C++ code. The processor is to be a diskless AT-compatible, which will sit on a LAN. The platform group, who live well North of here, have hit upon the idea that we don't need DOS. Philosophically, nobody does! But they suggest that we run the code on an empty box...no O/S at all. Assuming that such a C++ application could be downloaded to such a platform processor, I have so far arrived at the following 2 methods: - supply every interrupt/DOS call that would be used by the C++ application, which may not be very many given no disk stuff, or - replace library functions that do interrupts/DOS calls with own version that would avoid such things. My goal is to determine whether or not we'll be up a creek by going without an O/S. My gut feeling is YES, given the unknowns. I'd appreciate any comment on the matter, probably email only since this is a non-standard way to doing things. -------------------------------David Witherspoon------------------------------- D.Witherspoon@Atlanta.NCR.COM | "It's all just 1's and 0's you know!"
