[Dxbase] DXBase 2007 vs 2003

Mon Mar 22 23:58:24 EDT 2010

I've been using DXBase 2003 for many years now. It's been serving me 
pretty well, but I was thinking that it might be time to upgrade and 
take advantage of the inevitable improvements that have accumulated 
between v2003 and v2007. When I went to K3NC's website to investigate 
purchase of v2007 it mentioned that I should include a list of callsigns 
that I expected to use in the comments section of the order form. Is 
this something that is hard coded into the software such that I won't be 
able to use the software at some later date with a different callsign? 
Right now I have v2003 databases for something like 7 different 
callsigns (my current callsign, three club calls, and three old 
callsigns). I can load any of these databases upon program startup. How 
will v2007 differ in this regard?
Thanks,
