Graham,

Sorry about the lack of detail.

Here's more:

AVR Studio
Version 4.14
Build 589

WinAVR GCC 20080610

----------------code-------------

#include <avr/io.h>

void main(void)

{
	
	volatile int count;
	volatile int marker;
	char readB;
	
	
	DDRB = 0x00;	//all inputs
	PORTB = 0xff;	//pullups

	DDRC = 0Xff;
	PORTC = 1;
	
	
	count= 1;
	
	while(1)
	{
		count++;
		

		readB = PINB;

		if(PORTC & 0x80)
			PORTC = 0x01;
		else

			PORTC = PORTC<<1;

	
		if(readB != 0xff)
			PORTC = ~readB;



	

		if(count >250){
			
			marker = 0;

			count = 3;
			}

	}

}
----------------end of code
