Hallo Richard!

 RM> It was because somebody wrote that he never heard of DOS Latin 1.

I fail to see where it claims "Latin 1", although I have seen a few hits that
claim CP437 as upper or higher ascii which of course doesn't really exist
except in the minds of those who don't really know what they're talking about. 
However the particular link in question doesn't make such a claim.  In fact
they don't actually make any meaningful claim to anything.

 RM> They have asked!

Yes but there were only two answers, one of which is wrong while the other
lacking as to my true feelings on the question, not that it really matters in
any significant way.

Het leven is goed,
Maurice
