wire edm, HELP!

Hello,
I just entered the world of wire edm. We just got a charmilles 240sl.
I went to Chicago for a weeks training on it. It gave me the bare
basics but I need help. We will be using the cad system bobwire to
load our programs, I'm trying to get some software from them to assist
me with that progam. My question to you out there is could you give me
a title to a good book to get me brushed up on writing programs,
starters, for dummies like me. The only writing I did was in school a
long time ago. I usually run a mill and a lathe (conventional). I've
seen numerous books out there but I need the one for beginners. If you
got a good title let me know. Much thanks, Glenn in TN.
