Newbie question about Arrays

5 posts in this topic

How do I specify a variable to have another variable as the number of array elements.

Example $array[$i] 

Whenever I type

Global $array[$i]

An error happens saying something like I have used $i before declaring it. Sorry if it's hard to understand what I'm trying to say as I am still new.

LoomyGnarly,

Welcome to the AutoIt forums.

You need to define the $i variable before you use it - like this:

#include <Array.au3>

$i = 3

Global $aArray[$i]

_ArrayDisplay($aArray, "3 element array", Default, 8)

All clear?

LoomyGnarly,

Glad I could help. But when you reply in future, please use the "Reply to this topic" button at the top of the thread or the "Reply to this topic" editor at the bottom rather than the "Quote" button - I know what I wrote and it just pads the thread unnecessarily.
