Thanks Joe. As I said in previous post the thing is working OK now. Didn't know about the need to change the inc file for the internal oscillator, but I have now done so and relieved to find it still works. The [ symbol was intended to signify the start of the code.. seem to remember someone telling me that I should do that when posting code. I now have yet another seemingly inexplicable problem. I am programming in circuit with PicKit 2 which has suddenly decided to stop the circuit working if I disconnect it. I have a seperate power supply which is powering the circuit so simply cannot understand why it should stop working when I remove the PicKit2 . It wasn't doing it earlier this week so I am at a loss to know what I have done ( nevertheless I'm pretty sure that I know who is to blame again!)
Cheers
