Each program module developed in A4GL can run on the following platforms: Windows, Mac OS, Linux, iOS and Android.
In other words: you develop a module and it can almost immediately be used on all these platforms!
Develop once, deploy everywhere
No major programming effort necessary, you merely need to adjust the screen forms to the resolution of the respective device.

Learn and Install
Learn how you can use the VDC for your applications.
The VDC runs with modules written in A4GL. A4GL is an international, professional open source project, initiated by the British company Aubit in the mid 90s. VENTAS has contributed the graphical interface to this project in the form of the VENTAS Desktop Client which is now also available as a mobile app.
The VDC itself is free in its basic version. Maintenance customers receive additional features such as graphics in 2D and 3D. You can download the VDC for PC workstations from our website. For the mobile version use the Google Play or App Store.
The simplest way to use the VDC for your own applications is to download it and register. Then, you can find under “Options” access to the online documentation which will explain all the steps for you.
Contribute
We invite C++ and 4GL developers to participate in the VDC/A4GL project.
The source code can be obtained from GitHub or SourceForge. You can create a fork and send your code changes or simply notify us so that we can check and merge your contributions.

A4GL and the VDC are generally compatible with Informix 4GL, Querix or 4JS. The VDC offers many possibilities to make your 4GL application look its best.
Additionally, we provide server-side tools for reporting and document generation that were not available in the original language. The A4GL language advances the already fast and efficient 4GL language to fulfill modern requirements.
