Well, if your code sez:
openWindow(win,Modal)
puts(1,"Hello World")
....etc
then of course it will open the window, and then continue with the next line.
But that's just not good Windows event driven coding.
Actually, it's not Windows coding at all.
You can't write Windows programs like you write DOS programs. It just doesn't
work that way.
