Dear Rene

Thank you for the fast reply.

-Problem 1:
I did run make, not gmake, as far as I know this should not make a
difference?
To run Event, I tried
   Event
   Event 400 1 1  (since this was the call in earlier versions?)
I will try Event 400 0 7 1

-Problem 3:
In my case this worked in version 3.00/01 but not in version 3.00/06 and not
in 3.01/02
The reason is unclear to me.

Best regards
Christian
