Clascal

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Clascal was an object-oriented programming language developed in 1983 by the Personal Office Systems (POS) division (later renamed The Lisa Division, still later The 32-Bit Systems Division) of Apple Computer. 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 Xerox PARC's release of Smalltalk-80, v1 (which had been ported to the Lisa previously), and also by Modula.
