The forward declaration is not needed to"hide" the function:

No its not needed to hide the function is needed to declare it.

But only if the order you wrote them in is absolutely necessary.
(Which, from your example isn't clear.)

I have no idea if it is "absolutely necessary", I'm answering a question avoiding assumptions, it is a time saver though if you are not interested in finding out if it is absolutely necessary.

Thank you for everybody!
I didn't know, the order of of the procedures under implementation is important.
Thanks again!

Pascal is strictly declare before use. So if you call a function before it is declared (either a declaration
in the interface, or code in the implementation section), you need to declare the procedure header only forward.
This is usually not done as a matter of routine. I only have an handful of forwards in my framework which are hundreds
of units. (though admitted, in OOP code you declare more, so it is less needed)
In case needed look up "forward" in the manual.
