Ed,

Thank you again for this valuable information! I didn't realize that there were so many information so close to me ;-) (I'm talking about VFP help).

About beating the head against the wall, I already tried once, but I have to admit that it hurts a little bit <g> It's better start reading...

I agree with you about the importance of knowing about the details of OSes, Network, protocols and so on. I'll really try to learn more with the references you passed me.

Thank you very much for your kind replies (and apologize my bad English).
