Do you mean Java doesn't have global variables or I'm mistaken ?!?

I kept getting the error message
# UnboundLocalError: local variable 'cpt' referenced before assignment
where I really didn't expect to get such an error, and noticed in this
forum a lot of guys who know Python complain and talk themselves about
a "mess" (my 'cpt' var. is a counter incremented every time a method
gets called and I must sometimes re-initialize it to 0 inside an 'if'
statement: merely IMPOSSIBLE).

And why not ? Anyway SQL*Plus contains plenty of built-in commands
that allow you to format your output how you like: I'd like to
keep that functionality. And let's say that I want to do that for
the sole purpose of learning the handling of IO streams in Python !

I admit it. But I did *exactly* the same with Java (writing
the app I'm trying to port) but never got stuck into problems
