How interesting. I guess Excel really doesn't care whether the extension is
xll or xla. It does use Excel4, right? With 33 c files, it seems as if it
does quite a lot. I hope it doesn't do anything that is specific to Windows.
If it does, it will be much harder to convert. I do know that the latest
version of Excel supports xll's since it comes with one. Other add-ins are
shared libraries, the creator type is 'shlb'. Unfortunately, MS hasn't
documented how other's can create this kind of add-in.
I will try to dig out what I can about xll's on Mac. The code is somewhere
on my Mac. I remember I used something called a RoutineDescriptor.
