Thanks for the response.

Unfortunatey using the modified code below I get the same error message.

I am puzzled at the moment.

Any further suggestions???

#include <digitalWriteFast.h>
#define led 13

void setup() {
pinMode(led, OUTPUT);
}

void loop() {
digitalWriteFast(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWriteFast(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
