reset initial with array

Hi,
i read help but i dont do this.

I have:
DEFINE DATA LOCAL
1 #CIDADE (U25/30) init all <’_’>
1 #HABITANTES (N10/30) init all <0>

and i try:
reset initial #cidade
reset initial #habitantes

But i see error:
NAT0281 Index entry missing or invalid for an array.

But in help this option is possible.

How do i do?

reset initial #cidade (*)
              #habitantes (*)

simples as that … !

Thanks.
