[About error recovery in these programs]

I don't want to sound like a commercial, but the GMD-tools have a
lalr translator which is able to generate some error recovery without
user interference.

Me, just being rather lazy, thought it ought to be enough. And yes it can
guess the missing ';' from my pascal-tests and 'repair' the syntax.
Now this is only for the one syntax I'm currently working on, maybe
other syntaxes aren't this easy.
