[Gambas-user] Return an array in a function

[Matías Manuel Grandi]

First of all, thanks for your time and dedication!!!!

Basically, I'm not too oriented to OOP because....I'm not a programmer, I'm
just an economist. It's only a hobby.

But the most important thing to not moving to oop, or not moving
successfully, is that I started programming in basic, some scriping
lenguajes, PHP...and so on. So I'm not too familiarized with oop, and I
couldn't find a good manual about it (I'm sure it exists), adding that
gambas documentation is very poor.

BTW, your code is excelent, and shows in a clear way the benefits of OOP. So
I will take the code as start point, and I'll try to improve my oop with
gambas.

So I will ask many questions on the list...so be patient, please!!!!

Regards,
Mato.-
