If there are two things on DBC I don't understand well, its arrays and FOR NEXT commands. Arrays are confusing. FOR NEXT seems like it has no point. Maybe its just because I don't really get them. Could someone please list why these commands are useful and situations in which they are useful. I would greatly appreciate it.

If we're here to help others, what exactly are the others here for?

For/Next Loops:
You might want to make objects 1-4 a size of 34, you could do:

or...



Arrays:
Let's say you wanted 5 variables, and you wanted them to have random numbers, you could do -


or...


Now, try this with the for/next loop:




Both are very simple, and very usefull.

I made a tutorial on arrays.. I hope it helps. (the link is in this post if you can't find it)

Of course, Zotoaster's example should help too. Mine goes a bit further, but it starts there


FOR/NEXT:

It cycles a variable through numbers, starting at the first number, and ending at the last. Say you had "FOR v = 1 to 6". It will cycle the variable v through the numbers 1 2 3 4 5 and 6. In each cycle, it will do the desired action (i.e. what you put inbetween the FOR and the NEXT.)

Sorry if It sounds like I'm repeating Zotoaster.

You guys are officially awesome! That tutorial was very helpful, and now I can use FOR NEXT in my programs without wondering WTF I'm doing. Thanks! I would type thanks 100 times but then I would be spamming, lol.
