Not argumentative at all.

I should have know that because I have considerable experience with another PIC based BASIC system where you can peek / poke the OSCON register to change the internal RC oscillator frequency. And , I did not read the PBP manual very thoroughly before starting.

I do agree that the manual leaves a bit to be desired from a beginners standpoint. Aside from being unclear in places, I find some of the examples inadequate or irrelevant and not very "real word". But such is the case with a lot of products. Most of the effort goes into the software & marketing, while manuals / datasheets are an afterthought or a necessary inconvenience given a back seat . Good tech writing seems to be becoming a lost art.

I have found that looking at others well commented code is a really good way to learn.
