hello everybody i have seen so many posts on Arrays and i think i found out a way for people to understand it.

+ Code Snippet

DO
dim a(10)
for t=1 to 10	
	if mouseclick()
print (t)
endif
next t
LOOP

Ok in that code snippet you will recognize dim that is to make an array then i used the for statement i made 10 arrays you can also store things in arrays this just prints all the arrays on the screen not whats in them

I hope this helps

That code only makes the array, it doesn't use it...

This is how an array works:

+ Code Snippet

sync on

dim array(10)
for a=1 to 10
array(a)=a
print a
next a

wait key

First of all, you're dimming the array in the loop, which you shouldn't. Second, you're not using it... you just made it and then go onto something completelly different.

I guess your trying to help whipped but zotoaster does have valid points, your code does not actually do as you say. here is an example to clear it all up.

+ Code Snippet

rem setup the sync
sync on : sync rate 60

rem create the array
dim MyArray(10)

rem create a loop
disable escapekey : while escapekey()=0

rem with a loop print out your array locations 1 - 10 but not the zero location
    for t=1 to 10	
      print STR$(MyArray(t)
    next t
rem update the screen
sync
rem end your loop
endwhile
rem end your program
end

Firstly, when you make the array in the loop, you keep making it and it slows down the computer (I ran the program and watched my free memory go from 50mb all the way down to 0mb and my computer froze) so thats one thing down and then second, you made an array but didn't show how to use it, (Zotoaster mentioned both of those basically) and also the for loop and whats in it has nothing to do with the array.

Quote: "this just prints all the arrays on the screen not whats in them "

nope, it just prints whatever number t is. There is only 1 array and it's completely empty.

I'm such a n00b (Dark Basic Pro Guy is my older bro btw!!!)
