  In a recent message, it was asked whether FOR loops in Modula-2 had to
execute at least once, like the DO loop in FORTRAN.  It is, indeed, pretty
unclear from Wirth's description in his book (how many people besides me
consider the book a bad advertisement for the language?).

  I went and compiled a test program and found (phew) that FOR loops with
an empty range execute ZERO times.  The compiler was Logitech Modula-2/86
on an IBM PC.
