  Why Modula-2 rather than Oberon or Modula-3?
Oberon has a couple points which would have been nice
to incorporate into ISO M-2 (using a hex number with
suffix X for characters rather than octal with suffix B,
and allowing POINTER TO ARRAY OF CHAR).  But apart from that
Oberon is an inferior notation and a real step backwards.
  Modula-3 on the other hand improves on both M-2 and Oberon.
The format for numeric constants is much nicer (even C has a
better system here than M-2 and Oberon).  But as mentioned, M-2
is much more widely available than M-3.  Modula-2 also has an
ISO standard, although it has major problems in the area of I/O,
so people are continuing to use their old PIM modules until the
situation is fixed with a revised standard.
