REALbasic is a strongly typed language with minimal automatic type conversion. The file format contains window and control placement data and is proprietary, however, XML export and Visual Basic import functionality is provided. All source can be contained in one file, but it is also possible to have classes/modules in separate classes in the same way as most other languages or dialects (C programming language, Java, Visual Basic).

The IDE for the current version (5.2.4) runs on Mac OS, Mac OS X and Microsoft Windows. The professional edition can compile programs for all these platforms from the same source file. It can also access databases (Oracle, PostgreSQL, MySQL etc.).

The standard edition can only compile programs for a limited set of platforms, and does not access databases. A professional license allows you to compile to all target platforms (Mac OS 9, Mac OS X, Windows, and with 5.5, Linux), as well as access databases (including the built-in, single-user REAL Database engine), compile console applications and numerous other features.

REALbasic has a complete feature set supporting hash tables, QuickTime, serial, TCP/IP sockets, Apple Events, ActiveX, OLE, and API calls on Mac and Windows.

Here's some sample code to take the value from two editfields (called firstfield and secondfield), and add them and put them in a third field called thirdfield.

thirdfield.text = str(val(firstfield.text) + val(secondfield.text))
