Thanks for the info on wd 'qd' Bill
I ran into this problem earlier and used some awkward assignments to
the box (edit box) since I didn't know that the query could be forced.
Nice trick.
The empty list issue might be rectified by displaying an 'Enter tacit
sentence into edit box' message in the tdisp (listbox) if the box
(edit box) is empty. I think this might be a friendlier introduction
for users who forget to use a meaningful argument with display.
When you say 'graphic box drawing', do you mean the Unicode characters
or is there another way to display the box components in an even
cleaner way? Either way, I agree that the display should be made as
clear as possible.
Cheers, bob
