Dear Andy,

A shockwave ran through my body when I saw this VOLATILE stuff. I have been using something like in this in almost all of my projects.

void foo(uchar nm)
{
    unsigned char i;
    for (i=0; i<=nm; i++)
    {
        .....................
        .....................//In this function i is used nowhere
        .....................//Except the for(...) statement above
    }
}

In situatuion like above one, I use 'i' nowhere else in function otehr than mentioned. Do I need to use "volatile" keyword for 'i'. I would like to mention that my several machines are running absolutley fine as expected. I would like to also state that I never use loops for getting delays for generating delays I always use hard timers.

Thanks & Regards,
Prahlad Purohit
