    First of all, please read the instructions on how to post source code:

    Did you not notice in the preview that the presentation had gone wrong?
    Didn't you expect to see:

    static void delay( unsigned long cnt )
{
   while( cnt-- );
}

    Note that 'static' is a standard 'C' keyword that has nothing specifically to do Keil, nor ARM, nor with "this kind of function".

    You can look up the meaning of the 'static' keyword in any good 'C' textbook...
