Dan,
When the label 'Null Item' appears in the value portion of the display,
while using the 'Report All' command in query, may actually contain data.
I have determined that the 'null item' label is always associated with
character type data (X,U,..) and all it really means is that the character
strings starts with a non ASCII character (usually a binary zero). One
method that I've used is:
>Find ITEM_NAME < " " OR ITEM_NAME > "~~~~~~"
Where the quoted string is equal to the length of the item. Needless to
say that the above will perform a serial read of the dataset.
Regards
Paul H. Christidis

Maybe I should have made this more clear...
I'm wanting to search for NULL ITEM fields in Image/3000, not Image/SQL.
