Using variables in setting variables

I want to enumerate a variable as so:

$x = 0
Do
  $x+=1
  $Day$x = True
Until $x = 7

The above returns a syntax error on $Day$x (because it's only supposed to see one variable in the command). So basically, I want $Day1 = True, $Day2 = True, so on and so forth. Is there a way to accomplish this?

Welcome to the wonderful world of arrays.

#include <Array.au3> ; for debugging

Global $Day[7]
$x = 0
Do
    $Day[$x] = True
    $x+=1
Until $x = 7

_ArrayDisplay($Day) ; For debugging

You can actually do what you originally described with $Day1, $Day2, $Day3 but it would be a very bad programming practice and I personally strongly discourage it. That being said, it is possible with the Assign function. You'd be using it for totally the wrong reason. But for completeness, here's how:

$x = 0
Do
    Assign("Day" & $x, True)
    $x+=1
Until $x = 7

MsgBox(0, "", $Day2)
