The reason for my problem was a regional setting in VFP. "Use System Settings" was marked. That leads to a default of "SHORT" for the Date Format. And Short (and Long) create errors when one tries to use a table with values like {^0209.20.02} or {^1071.10..03}. These are obviously typpos but are accepted with every Date Fromat other then Short or Long.

I removed the mark at "Use System Settings" and the errors are gone.
