Well, two things...

First, I believe that you are using the term CLOSE improperly here.  The
only thing (besides exiting) that will CLOSE a lookup is CLOSE.  However,
"if not lookupname" does not mean the file is "closed".  It means "did
the lookup fail?"  Also, a failed lookup does _not_ close the file.

Remember -- the lookup did succeed.  The fact that you deleted the record
that you found does not change that fact.

Finally, I'm not sure what you mean by "[you] can't CLOSE after [you]
delete [the lookup]".  First, you can certainly CLOSE the lookup if you
want to, regardless of the success/fail state.  Second, unless you are
finished with the file, why do you want/need to close it?
