David,
Further to last post, I downloaded and installed OpenOffice but found that
the only Lotus 123 formats that it translates are *.wk1, *.wks and *.123. So
it will not translate *.wk3 or *.wk4. I don't know if there ever was a *.wk2
format.
In the end I had to use my wife's Excel2003 and change the registry to allow
the opening of my Lotus files and then to save them as .xls files.
Seems that the DataViz product would do it but that's $50 a pop.
So it goes...
