Combine variable name

[dainiusb]

Local $abc1 = 2
Local $abc2 = 3
Local $abc3 = 4

MsgBox(0, "", $abc & 2)

Something like that. $abc + 2 = $abc2 Can this be done in AutoIt?

Yes: Look at Eval() in the help file.

I don't understand how to do it. I see Eval and Assign as completely different things than I need.

From examples I understand that Assign is used to assign data to a variable and eval finds out the value but how is this useful? I don't get how it works.

Eval takes an expression. This means a string is acceptable rather then an actual variable.

Example

Local $abc1 = 2
Local $abc2 = 3
Local $abc3 = 4

For $1 = 1 To 3
    MsgBox(0, $1, Eval('abc' & $1))
Next

All 3 variables are shown in the loop by using the expression of 'abc' & $1

That's a better example than the one I was about to post.

Ooh! Now I see it. Thank You.
