>You're lucky that you can do so. Most often, such a field is an afterthought, when you already have trucks full of records in such a table, and you can't rely on having the value in old records properly filled in. So you go with .f. being a default for new boolean field in old records, and then name it so that the value of .f. is the default. Thus my forced choice for such fields is "Inactive", "Deleted", "Removed" and such words with implied negative.

During designing of this feature that involves this field, as may have read my threads here, I have changed the name and the type of the field at least 3 times. What I thought would take me a couple of hours, ended up taking a few days. And I am glad that I took the time and I am happy with the result.
