Hello again dman. In the meantime I was able to get the function prototypes to work. I had already done the setup steps and I think the compiler is setup fine. The problem, I think, was that I was trying to use makeheaders without really understanding what it was doing. I ended up making the function prototypes manually. Now I have everything compiled without warning or errors.
However, now I have a new problem. One of my exe’s bombs out at runtime. I can’t see where this command line compiler has a debugging / runtime environment. I vaguely remember a debugging environment for Turbo C, but the last time I used it was in 1992! How can I step through this code in a debug environment?
I haven’t used this compiler for a looong time , but as I remember you have to do a few small things to configure it or it will not work properly. Heres a link that shows how to configure it http://edn.embarcadero.com/article/21205 , you can also google set up Borland command line tools .
