When the function is used, the resultat is always: "{}", so I do not
Know if:
-the function is not well defined, or
-the output value can not be an array

I have received your response about how a function, which output value
is an array, can be created (e-mail 10.04.99), but I get always the same

resultat. Would you be so kind as to write an example of a function,
which output value is an array ?

Thank you very much.
