Gabor,

Very nice output of this option. I get:

ene 1988 feb 1988 mar 1988 abr 1988 may 1988 jun 1988 jul 1988 ago 1988
       5        6        5        6        5        3        7        4
sep 1988 oct 1988 nov 1988 dic 1988 ene 1989 feb 1989 mar 1989 abr 1989
       7        8        6        6        6        3        4        6

Thanks!

Antonio
