Wow, thanks for the clarification! I never heard that one before.

As Steve implies, neither Level 1 nor Level 0
described a language that was useful for more than small programs.
Pascal was designed for teaching purposes, not to be industrially
useful, and the ISO standard was, in that sense, a joke because
any Pascal usefulness came from proprietary extensions anyway.

There was some discussion of an extended Pascal standard, but I
don't think this ever came to fruition. That being the case,
the best approximation we've seen to a really grown-up Pascal
standard is Ada. If memory serves, Red, Blue, and Yellow were genuine
extended Pascals. Green was not, but OTOH it's a pretty close
derivative.
