Pierre Orphelin,
thanks for your effort and the confirmation that I understood the problem
correctly. You described one of the points I listed (""- testing all the entry-
and exit-conditions ... and including an other cause of the fault.").
No, no I won´t scream - I´ll make my homework !
In this case it is easier without TS ;-)
(Nevertheless that´s no reason to sell it.)
Greetings from Mannheim,
Ulrich
