I am trying to understand 16-bit register,I don't understand how to write them as seperate registers,could someone give me an explantion.

Thanks

Do you mean register variables? Register variables are set to whatever the compiler feels fit. They are just a recommendation to the compiler. The compiler will do it if it can.

Are you working on a 16-bit machine or a 32-bit machine? I'm not sure if you can get 16-bit registers on a 32-bit machine. You could try "register short" and check the code generation.

Are you using inline assembly or something? C++ has no concept of registers since that would be platform dependent.

No what I was trying to figure out, is why the debug in Visual c++ express 2005 dose not want to run. I have check the path and everything else I could think of but it simple won't work. I thought maybe I was writing the registers incorrectly but that is not the problem. The program builds fine but won't run.

What have you got? Is it something simple like

#include <iostream>
int _tmain ()
{
   std::cout << "it works" << std::endl;
   return 0;
}

If you set a breakpoint at return 0 and press F5, you should see a console window pop up and the program should break. See if you can get that far.
