Protel 99 SE SP6 general question(s).

[Franklin]

I'm going to give Protel 99SE SP6 a try. Will be using it for design of
audio pcb's. A couple of years ago I have worked with Eagle which was very
basic and easy to work with.

What should I keep in mind when working with Protel regarding component
placement, inductance, resistance, etc.?

Thanks for any info.
