WHY NOT USING GAMBAS?

Writing It's Own Language Is Funny & Exciting Easy To Learn With Something Visual, Easy & Basic Development Environment Is Easy To Use Fast To Development Something Simple Application/Software An Object-oriented Language Components Are Designed To Be As Simple & Coherent As

Possible You Can Write Software That Is Independent From The Graphical

Toolkit & The Underlaying Database Management System Good To Teach At University As Basic Programming Language To Make The Power Of GNU/Linux Libraries Easily Accessible Last, But Not Least : GNU/Linux Is Free, Powerful, Secure & Cool

THE GAMBAS FUTURE

✔ New Development Environment✔ QT & QTK+ Components Completed✔ Controls Bound To Data Sources✔ Report Designer✔ DBUS Protocol✔ Making Web Applications✔ Help Porting Visual Basic™ Applications✔ Object Persistence System✔ And Many Moore..
