Roxanne,

I know, that logical field could be either true or false. But, for example, when you create your table with logical field, this field remains empty unless you populate it... What's why I'm asking. Anyway, it's not a big problem, I think, we can live with this. My colleague just noticed the difference between old output table and new one...

I checked, that we have no this field in our DataBase, so it's definetely calculated field...

>>I have a logical field, which I want to populate with .t. on some condition and leave blank otherwise.
