It sounds like you want to use a class.
Why would you not just use a class if you want to store state?
Local coding conventions or programmer skill levels may preclude it.
I don't feel my program needs a class.
But in this case it sounds like a class is the best solution.
Why would you "feel" that you don't need a class when you have a
situation where several functions share common state? That's
almost the definition of a class.
Also i have been told to stop using classes by some very

Really? What reasons did they give.
Unless they are talking about very specific circumstances
that doesn't sound like good advice!
It's confusing being told different things.
Software engineering, like any branch of engineering, is about learning
to use many different tools and selecting the best set for a problem.
There are cases where classes are not in the best set, there are cases
where many global variables are a good fit. But both of these are the
exceptions to the rule and the engineer's job is to identify when a
genuine exception exists and make the right choice. There is never a
single right answer. Sorry, but that's life.
