Hello again,

....
Won't be even the blink of an eye if there's only one call during a calc
cycle, but can add up if there are lots of multiple calls and multiple
iterations, and it adds only a few bytes to the code.
....

Hmm, if it comes to speed, IMHO VBA should not be used in this
"pathological" case anyway. A simple worksheet formula would do...

Bernd
