# Case Sensitive setoption('OptionExplicit','ON')

Not sure I understand what the objective is here. There is already a SetOption() for CaseSensitivity.
Quote:

By default, all string comparisons are case-insensitive. Setting the CaseSensitivity option to ON instructs KiXtart to make all subsequent string comparisons case-sensitive.



Which is pretty much the same as:
If $Var == 'CaseSensitive'
...or is it about making varnames themself case sensitive?
$Var = 'CaseSensitive'
$var = 'casesensitive'
