well done again Bruce. I was aware of this TRSIO line since i've never use this before considering that PBP was suppose to do. But after experimenting i realise that was important to include in this case. I'll use this TRIS in future as a safe programming way.

that's for sure there's many way to blink a led. XOR function are one example . code also working without GPIO=7 but it's also a safe way.
