Could be that it never selected other than the whole file. Are there   
select statements to further refine the results which might lead you to   
believe it was working?

CHOOSE key "" ; that's quote quote with no space
will choose the whole file. Sort of like saying choose key parm and then   
entering nothing in response except in this case Quiz will ask you if you   
want the whole thing. Certainly works this way in 8.19 and I'm pretty   
sure it did in ealier versions.

Try CHOOSE key " " ; that's quote space quote
and you should get just the records with the blank key.
