incrementing the variable name

[iamtheky]

$size =  ubound ($array) - 2
for $i = 0 to $size step +1 


$read = _GUICtrlTreeView_Add($hTreeView, 0, StringFormat($Array[$i]))

so this runs through an array and sets it to tree view just fine. I would like to increment $read in some fashion (any fashion), so that if I were to do this in a loop each individual line would have its own variable.
