I am using this statement which I derived by trial and error, to change the display colour: disp_setattr(0x0041 + 45040);

It works fine on my PC running Win 98 and also my lap top running ME, but when this command is encountered when run on my PC at work, running NT4, the program exists with no error messages.  Am I using the correct format for this command?

Many Thanks
John

The functions in "disp.h" probably only work in MS-DOS and MS-DOS based Win32 Operating Systems (Win95, Win98, Wini-ME) because they do things at the hardware level which isn't allowed by an NT class Win32 OS (WinNT, Win2000, WinXP).

You could try recompiling the program as a native win32 app. The disp functions will work then.
