@Plutonix and Ken White sorry lads, since my old question wasn't getting rereviewed after I edited it to your suggestions (plutonix) I thought I'd make a new question with more questions and a better focus. My old question doesn't have answers, so could you please give me a chance. I'll delete my old question or whatever suits your fancy, just step back and let me consult some programmers — Billy Bob 27 secs ago
