Your numbers are correct, but why don't you just try the built in
functionality?

Or if you want it in code do it the easy way;
If Application.Calculation = xlCalculationManual Then calcmode "Manual"
If Application.Calculation = xlCalculationAutomatic Then calcmode "Automatic"
If Application.Calculation = xlCalculationSemiautomatic Then calcmode
"Semi-Automatic"

John,
Thanks for that - I was not aware of the Info("recalc") function.
But:
It has the same "problem" as my UDF: when switching from automatic to
manual, the function would not update and remain on automatic.
Can we do anything about that?
(I work with 2002/SP3)

There is really nothing that will do it all completely automatically.
Application.Volatile will force a UDF to update but calculation has to be on.
You can update it on a selection change of any kind but only by recalculating
the whole sheet(which defeats the purpose) or by knowing where each function
is and recalc just that cell.
