1) You will not get answers on Turbo C++ in a Visual C++ forum. Your code is proprietary to Turbo C++. It is neither compatible with Visual C++, and I bet none of those calls are compatible with the Windows OS.

2) Why are you using such an outdated, old compiler such as Turbo C++? The compiler is almost 20 years old, therefore does not reflect the current C++ language.
