[Gambas-user] Another basics

[M. Cs.]

Hello Fabien,
and I also think it would be nice to hear about how to keep the code
clean. I have to rewrite the things in order to have a program without
unfreed allocations.
What I intend to do is to use more private variables on modules and
well defined functions to access to them across the modules if needed.
