Thanks..
so its basically as I thought?.. or as Im used to.. just like defining a variable.
I have somewhat of a programming background.. just not in C or low level languages..
I am used to doing things more like this:
var varName:dataType = value;
var someText:String = "Hello World";
arrays are handled a bit different too I think.. which should be....um....fun!? LOL
Still not really clear on how/why they keep re-using the uchar var over and over for different equations/events (but I dont see the output saved/updated anywhere.. like its just overwritten on the next line??)
