This is an implementation of the programming language Borland C. It is a compiler, written in C++ for the MS-DOS platform that generates x86 machine code for the MS-DOS platform. It is proprietary software. Dependencies To run this implementation, you need: an implementation of MS-DOS (we suggest DOSBox) Commentary The source code for some of our projects was developed with Borland C++ 3.1 (although it is was written in C, not C++.) It may use Borland C++-specific extensions and libraries. Borland C++ 3.1 is not free software, although you can apparently download a set of Borland's later tools free of charge. I don't know if they'd be useful to compile these sources. Note that there are no projects at Cat's Eye Technologies that strictly require Borland C++ anymore; they've all been converted to use portable features (such as ANSI Terminal control codes) and should be quite buildable with any conforming C99 compiler. Note also that there are no projects at Cat's Eye Technologies that have been tested under Borland C++ recently.
