Hi V,

'---------------
It works fine, many thanks.

However, I cannot still understand why I have to use an intermediate
variant array "arr" instead of using directly the function name "b",
since both of them are variant. Where is the difference between the
two?
'---------------

You have named your function as b and the
function expects a single range argument.

Therefore, attempting to pass multiple Integer
(or Long) values in the line:

b(i, j) = b(i, j) + 1

will cause the encountered problem.
