I have a simple question.
What is the significance of the $ as an attribute name?
Are their any "special" attribute names?

Also, I am about to standardize my standard attribute names, any advice or
suggestion will be appreciated.
Some of the features I want are:
Good BOM output, alternate mfg/part numbers, vender lists, internal number,
value, specifications...

I have 3 prototype board, and I am about to rework them for production
boards, and want to do it nice and neat.
I am using PowerLogic 1.2, but I don't think this has changed much.

Best regards,
Giles
