{{More citations needed|date=March 2025}} '''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]]).<ref name="k304">{{cite book | last=Jensen | first=Cary | last2=Anderson | first2=Loy | title=Programming Paradox for Windows | date=1993 | isbn=978-0-7821-1018-0 | page=24}}</ref><ref name="j630">{{cite book | last=Burns | first=Patrick J. | last2=Weingarten | first2=Jan | last3=Clifford | first3=Ted | title=The Visual Guide to Paradox for Windows | publisher=Ventana Communications Group | date=1994 | isbn=978-1-56604-150-8 | page=443}}</ref> Paradox, now in its 11th version, is a constituent of Corel's [[Word Perfect|Word Perfect X3 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 (software development process)|development environment]] for creating database applications for Windows. ObjectPAL is not a full free-standing [[object-oriented language]]. It belongs to the family of languages inspired by [[Hypercard]], with influences from PAL (wherever functionality could be kept the same), [[Smalltalk]], and Garnet (a UI language created by [[Brad A. Myers|Brad Myers]]). While its objects do [[Encapsulation in object-oriented programming|encapsulate]] [[source code]], there is no support for [[Polymorphism in object-oriented programming|polymorphism]], and only a very limited [[Inheritance in object-oriented programming|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 for [[Microsoft Windows|Windows]] 1.0 in 1993, which was then owned by [[Borland]] Corporation, ObjectPAL was born. Version 1.0 was quickly succeeded by version 4.5 that same year. It can be used as such as a [[Scripting Languages#Server-side|web server scripting language]] when combined with the Corel Web Server Control OCX, which implements a server API similar to the [[Common Gateway Interface|CGI]], and its standalone console, the Corel Web Server. == See also == *[[Comparison of web servers]] ==References== {{Reflist}} {{Authority control}} [[Category:Domain-specific programming languages]] [[Category:Borland]]
