use NAN in 0
Select NAN
liRecc=RECC()
APPEND FROM aar TYPE xls

This should append everything and not just the ones in the condition. If the table is still empty then you need to check whats in aar.

Whenever you get a problem that you cant figure out I always find it best to simplify things and then gradually build it up. This allows me to identify and understand which part has gone wrong.

Just my way of doing things but effective.
