The curly braces aren't really needed.
Heh. Of course not. And I should have just used a loop...
Now, I have figured out what I was doing wrong, at least with regard to power nets...
Where I'm still scratching my head is on nets where the connection is not actually drawn in the schematic. For example I saw a schematic where there was a IC that fed into a terminal block. Rather than draw all the lines the output from the IC was labeled and the connection on the terminal block were correspondingly labeled. This made the schematic less cluttered. But how did the nets get connected for use in creating the board layout?
Does my question make sense?
