I would love it if someone would write a white paper on this. It might seem obvious to some people, but to me (and probably a lot of others who are learning programming as they go) it is horribly confusing.
I have some ideas on how to do this, but the problem is that this is not one of those things I can do one step at a time, rather I have to do it all in one big step, then when it doesnt work I will have to try to find where in the mass of code the problem lies.
