Hi Anand, and everyone else who responded to my plight,

Anand, Your suggested code worked like a charm, on the first try--THANK YOU !!!

I am thrilled to have it finally working. I'll need to go troubleshoot why my code did not work, so I can better understand my mistake and how not to repeat it in the future. And, whew--I'm sure glad to not need that other circuitry that X10pro showed in between the PIC-chip and the psco5.

Fantastic, and thanks again,
Guglulenun
