Title: Clascal
| Old | New | Line | |
|---|---|---|---|
| 1 | + | **Clascal** was the first working prototype of [[Object Pascal]] developed in 1983 by the Personal Office Systems (POS) division of Apple Computer (later renamed to **The Lisa Division**, still later to **The 32-Bit Systems Division**). It was the first true object-oriented version of [[Pascal]]. | |
| 2 | + | ||
| 3 | + | Clascal was an extension of [[Lisa Pascal]] and strongly inspired by Xerox PARC's release of Smalltalk-80 and the language [[Modula]]. In turn it laid the foundation for the development of Apple's Object Pascal, later referred to as [[Mac Pascal]], when *Object Pascal* turned into a generic term. | |
