With a few relaxations and extensions, you can get a surprisingly useful language out of the rigid Pascal, as evidenced by Turbo Pascal, one of the most popular (and practical) programming languages in the late 80ies / start of the 90ies. mkb.

It was not a language. It was a product in the hand of a single company. The difference is that a product can die at the snaps of a marketroid, no matter how nice or how diffuse it is. Andrea

Of course it is a language, just not a standardized one (if you include Borland's extensions that make it practical). But does that matter? With the exception of Scheme, none of the languages that are the object of discussion of the newsgroups this thread is being posted to, are standardized. Yet they are all quite popular. And btw., I haven't used Pascal in a dozen years but my latest info is that Turbo Pascal still lives in the form of "Delphi" for the Windows platform. Surely not "dead" as I understand it. mkb.

That argument might still have been active at the inception of Pascal, I'm not sure. But Pascal *does* have a goto statement, although you were punished a little for using it (numeric labels only, which had to be declared before use). And surely no-one was arguing against structured programming by the time Modula came along, much less Oberon. The restrictiveness of these languages was mainly in the type system, which is quite a different issue. And, as has been pointed out, relaxing the type system of Pascal just a little has resulted in a very successful family of languages (UCSD, Turbo, Apple Pascal, etc.) -- Greg Ewing, Computer Science Dept, University of Canterbury, Christchurch, New Zealand http://www.cosc.canterbury.ac.nz/~greg
