The compiler did not like your @ line.

It felt that three of the aliases were unknown.

I commented out the whole line and the program compiled, programmed and worked exactly as I imagined it would.

I guess I have to investigate the items in the @ line.

Meanwhile I need to pick a light sensor chip for an incandescent light bulb. Got any suggestions? I have to purchase this on line. Our local Radio Shack has no such items.
