clearly sometimes you have to be VERY specific, I smiled when I saw this great example of that need.

void delay(int num)   // timer 							
{ 
	int i;
	for(i=0;i<num;i++)
	{	
		TH0=0xfc;
		TL0=0x67;
	}	 
}

many many times it has been posted "for delays use a timer"

the above is a great example of the difference between "following the letter of the law" and "following the intent of the law"
