Hi Piter,

Life is good, thanks. Glad to see you're still in action. Are you
still maintaining the batch script to build QuantLibXL?

I don't remember the discussion and can't find any mention of it in
the archives. But looking at it now I see the problem, that the
constructor of the Business252 class expects an input argument. This
is not supported by the design for enumerated datatypes. The user
supplies a string e.g. "Actual/360" and the system automatically calls
the default constructor of the corresponding class e.g.
QuantLib::Actual360(). There is no mechanism for an argument to be
supplied to the constructor.
Could the class be reworked to support a default constructor? If not,
perhaps we could expose it as a proper stateful object.
Thanks,
Eric
