Using the symbol attributes "hardwires" the net name, but the separate power and ground symbols allow netnames other than what otherwise would be specified in the symbol.

I like this method of separate power and device symbols so much, I will start using it for all my future work. It certainly does make the design clear and is more versatile. Thanks for the links. I will check them out. It might be a good thing to change the symbol library packaged with gEDA/gschem to reflect this method. BTW: The example links were "not found". Thanks. Girvin Herr >
