Thank you for your reply!
I tried it and put flush.console() after each print(...), but again nothing
happend until the calculation was finished. I don't think the problem is the
"output procedure".
It looks as if R would crash when I click on the button "OK" (but it does'nt
crash, it is only calculating and doesn't response until it is ready).
So I think the function foo(...) has to be called in another way (?)
