Clascal

Clascal was an object-oriented programming language developed in 1983 by the Personal Office Systems (POS) division (later renamed The Lisa Division, then later The 32-Bit Systems Division) of then Apple Computer, later renamed Apple Inc. It was an extension of Lisa Pascal, which in turn harked back to the UCSD Pascal model originally implemented on the Apple II. It was strongly influenced by the Xerox Palo Alto Research Center (PARC) release of Smalltalk-80, v1 (which had been formerly ported to the Lisa), and by Modula. Ultimately Object Pascal evolved into the language of Borland Delphi.
