Okay so, I had a look at the Assign and Eval functions and I don't believe they would've helped me accomplish what I wanted to. That or it didn't click with me. However, you're right about arrays being the better option. I looked into arrays more and was able to accomplish my task with the following test code:
AutoItSetOption ( "ExpandVarStrings", 1 )
$VarAA = 1
$VarAB = 2
$VarAC = 3
$VarAD = 4
$VarAE = 5
$VarAF = 6
$VarBA = 7
$VarBB = 8
$VarBC = 9
$VarBD = 10
$VarBE = 11
$VarBF = 12
; Declaring a 2 dimensional array
Global $Var[2][6] = [[ $VarAA, $VarAB, $VarAC, $VarAD, $VarAE, $VarAF ],[ $VarBA, $VarBB, $VarBC, $VarBD, $VarBE, $VarBF ]]
For $a = 0 to 1
For $b = 0 to 5
If $Var[$a][$b] = ($a*6)+$b+1 Then
$VarX = $Var[$a][$b]
MsgBox ( 0, "Test", "($a$*6)+$b$+1 = $VarX$" )
EndIf
Next
Next
Thanks a lot for the guidance!
