This is excessive. Maybe you can think about if your variables can
be put into a meaningful class. An object of this class contains all
your relevant variables and you can pass a reference of that object
(as a container for the variables) to a function.

If there's no sensible grouping of variables into classes but you
don't have dozens of variables, then you could try ByRef [1].
