While there may be general agreement that Pascal is a great teaching language and a weak systems language, I believe that early versions of mac operating system (system N, not OSX) relied heavily on a modified version of Pascal. Perhaps Steve did not get the memo.
Becaues Clascal/Object Pascal had an enormous number of non-standard extensions to make it a much more system and apps oriented language than the 1973 version. I believe Bill Atkinson was involved in the decision. Same story with TurboPascal and Delphi.
Walter's complaint is partially that it needed extensions to do anything non-educational on 1973 hardware. This is true, but to me is vaguely non-sensical, as it clearly had not been designed for that and was labelled as such.
