Should the info attempt to be a Pascal language tutor ? ie. Should it cover FOR, WHILE, REPEAT etc. Surely most people coming to GPC will do so knowing Pascal from elsewhere. Since the world at large seems to prefer C (or Cobol), it seems to me that we don't need to worry too much about explaining the standard contructs as only those who have already chosen Pascal will be interested in GPC. If we do want to include standard constructs, we might derive our explanations from one of a number of existing books eg. Programming in Pascal, by Peter Grogono. (Addison-Wesley 0-201-12070-4). This book explains the FOR loop by its equivalent code using WHILE. I know this is copyright, but it (or similar) should give an idea how to explain these basic constructs. I think LALR(1) is the algorithm used for parsing. The syntax definition language is Backup-Naur Form, known as BNF. The Grogono book I mentioned doesn't use it, it uses syntax diagrams instead, but I'm sure someone can provide BNF for GPC. Whatever goes in should certainly be checked for English grammar and usage by a native speaker, or one of the German members of the list, who seem to write extremely good English. Regards, Richard.
