REALBasic was created by Andrew Barry, who has since moved on to creating ExtremeBasic. It was originally called CrossBasic due to its ability to compile the same programming code for Mac OS and Windows (although the ] was Mac only). It was then redubbed REALbasic by REAL Software when they took over development in ]. The IDE is now available for all three supported platforms (with the exception, as of February 2006, of ] ]).

] ] ].
The source file format contains window and control placement data and is proprietary; however, ] import and export and ] import functionality is included. All source code can be contained in one project file, but it is also possible to have classes/modules in separate files in the same way as most other languages or dialects can. REALbasic compiles directly to ] for each platform that it supports (Mac OS X, MS Windows, Linux).

⚫ There are two versions of the ]:
* The professional edition can compile programs for ], ] and ] (plus ]) from the same ] file; it can also access ]s (], ], ] etc.) including the built-in single-user REAL SQL Database engine based on ]; it compiles console applications and has numerous other features.
* The standard edition only compiles programs for the platform that the IDE is running on (either Windows, Linux or Mac), and does not allow access to ] other than the built-in REAL SQL Database.


⚫ ]:
Both versions of the IDE permit building the application ] by dragging the controls from a palette to their parent window. Layout of the controls is helped by the IDE that permits aligning them (both horizontally and vertically), and which gives informations about the distance between controls, or between a control and the window borders.
