There is a great little book called "What's M.I.D.I." It is probably in it 7th edition by now. Go to a reputable book shop and give them this code
ISBN 1 872601 13 8.
It will start you off on the right track, I do have to say that SScientist is the main man for M.I.D.I. on this forum and will always point you in the right direction.
