variable variables

Can you make a new variable each time something happens ... e.g. first $1, then $2, then $3... etc ?

I am not that great at autoit but I might be able to help since there are not very man people on. Could you rephrase the question? Do you want to add to the variable and make it bigger?

No thats not it

I'm trying to record multiple bits of information at different times and I need a new variable each time to keep it...

Bleh I cant explain it

You may want to use Assign() to create your variables and then use Eval() to use them.

Small example

; Create variables
For $i = 1 To 3
    Assign('var' & $i, $i * 20)
Next

; Display variables
For $i = 1 To 3
    MsgBox(0, IsDeclared('var' & $i), Eval('var' & $i))
Next

Edit:

But using an array could be easier if suitable.

YAY I can use arrays now! took me a while to get it right but it was exactly what I wanted! (I tried assign and eval but I still dont understand them)

but I have a question... when starting the array I used Dim $Array[1] like in the example but why do you have to include the [1] to use the array? It's annoying having a first blank

An array is like a box of a dozen eggs. The box is the array in total of 12 elements ($box[11]). To get your fingers on the first egg, then you need to following a rule governed by using a number as an index. So you would use $box[0] to access the first egg, $box[1] for the second and so on. Arrays in AutoIt start from an index of 0.

Look here for more help with arrays.

Have a look at the _Array* functions (help file).

#include <Array.au3>

$avArray = _ArrayCreate("Jim Bob")
_ArrayDisplay( $avArray, "Array" )
_ArrayAdd( $avArray,"Marry Ellen")
_ArrayDisplay( $avArray, "Updated Array" )
