I'm about to experiment the code protect option in programming PIC16F84A. Anybody willing to tell me what this means?

May you explain us the principals of making code protect?

It's been a long time since my last post. I asked this question because, with your help( also with other guys), I'm now beginning to accept orders from my friends about projects using PICs.
Some say its better to code protect my programs to prevent others from duplicating it.
Anyway, if I get it right, it's ok for PIC16F84A to be code protected, and it can still be reprogrammed.

Can you password protect???
can the chip be protected so others cant read it and be able to reprogram with updated code latter.
I've built a device for farmers, and don't want someone to be able to read the chip and make there own.
I share code, but when I sell a product......
kentken said:So, like on a 16F872 I will be able to lock the code, then latter rewrite the whole program?
The data sheets make it sound like when it is protected you wont be able to reprogram.
