Newbie: find, search command

[Frank D. Engel, Jr.]

Yes, but a cr at the end will show a blank line at the end of a field.  
Remember that list boxes are fields, and the selectable lines are lines 
of text from the field.  Since you can hit return/enter and add a blank 
line at the end of the field and have it displayed, you will also see a 
blank line at the end of a list box.

The original poster specifically stated that he wished to display these 
results in a list box (which is a field), so this is definitely an 
issue for him.  Trust me, it took me a while to work this one out 
myself, and I've been using something similar quite heavily (although I 
let PostgreSQL do most of my sorts and searches for me -- I just format 
the results...)
