Guys , let's stop this argument.
It's fairly obvious Psmith wants to use this but doesn't know how , and is supposedly a failure on our part and not his , and since he does not understand simple concepts a 13 year old can understand (Je suis treize ans , aussi) he must have it his way and no-one elses.
Honestly, come the fuck on!
What is so hard about variables? Exclusion? Z Depth? Function?
I must say they are fairly obvious. What do you think EXCLUSION means? Oh , possibly excluding , but probably not. Z Depth? Oh , how about depth on the Z axis? Function? Oh , well if you have even gone near standard grade maths , you should know about functions.
Christ , the ignorance of this person bewilders me.
