I think most people do it... I do, but I use lowercase for the prefix.

Yeah, for my personal contributions, some components, etc. I did that
(and still do).

Okay Guillermo, thanks. The same as Marc above.
I use prefix "u" just only examples.

The Pascal programmers has dislike "_" character, maybe just for
constants, I think.

That's what I was talking about! I'd be surprised if this was not
happening... even after the explanation of Marco van de Voort.

Yes, work for them... but the namespaces is very large in Java or C#.
I like use, some times, the sintaxe: unit.function.
Because of name conflicts of functions or prefix (also) the functions
(besides classes), to not use name of unit as a prefix.


CONCLUSION:
I'm not a newbie programmer, even though my question says otherwise. I
just like to know how the best programmers work in your daily. Some
times I find some ideas to making my work better.

Thanks all.
