>>>>>I would like to have a view parameter that works like a logical, but uses a date field. I have a date field that is either empty or has some value. I would like to bring down the records that are either empty or have some value (regardless of what the value is). Is there some way I can set up a view paramter off of the date field to provide this functionality, or do I need to create another logical field?

I think the simplest way is to use programmatic Select ... into Cursor, or you can use two views.
