Ciao Robert,

ok.. no problem at all. The community just give suggestions and I'm sure
Dirk will figure out the very good way for that. In the meantime
I just want to thank you for the nice piece of software you made (RXclus)
That sofware has improved my LOTW activity hi.

Sorry for off-topic ;)

Hi Fulvio (and Dirk),

Many thanks for your comments about my proposal.

Well, what you suggest is logical and I did it already for the search 
functions in RXCLUS 2 or 3 years ago. But I must say I got quite many
from users who did not understand the syntax change and were believing they 
did not get the expected answer because of a software bug !

So I guess Dirk will never implement this function if he expect this will 
cause trouble.

Even if this is maybe not optimal, I believe it's best to keep the current 
behaviour as default and add a simple parameter to be used only when an
match is needed...better this then nothing!
