ObjectPAL is short for Object-Oriented Paradox Application Language, which is the programming language used by the Borland Paradox database application (now owned by Corel).
Paradox, now in its 10th version, is a constituent of Corel's Word Perfect 2002 office suite, for 32-bit Microsoft Windows. The language is tightly-bound to the application's forms, and provides a very rapid and robust development environment for creating database applications for Windows. ObjectPAL is not a full free-standing object-oriented language. While its objects do encapsulate source code, there is no support for polymorphism, and only a very limited inheritance concept, which is wedded to objects on a form which can be controlled by code placed on a higher object in a form's object hierarchy. However, for what it is, ObjectPAL provides a wideranging and versatile language for creating Paradox applications. The syntax and structure of the language resembles Visual Basic, but knowing Visual Basic would only help someone new to ObjectPAL in the sense that any other programming skill would be transferable to ObjectPAL. ObjectPAL was the successor to PAL, which was the Paradox for DOS programming language. With the advent of Paradox 5.0 in 1994, which was then owned by Borland Corporation, ObjectPAL was born.
