RE: what happens if 2 INTs occur at same time

[Jürgen Klemt <jk@cellware.de>]

Hello Shimon,

I would be happy if we would run UNIX. No, we run it on PC. I think the reason
is that it is a unconventional pdf document, I noticed that you can't select one
word of a line sometimes. If you try it you always get the full line.

Regards, Jürgen.
