why I have this error???
MENUS.C(245): warning C206: 'wbyte': missing function-prototype MENUS.C(245): error C267: 'wbyte': requires ANSI-style prototype
Sounds like something to do with Floating point (maths).
Are you using the free evaluation tools?
Remember that one of the limitations of the free evaluation tools is that they don't support floating point...
