It seems to make sense in Fortran 77 (possibly due to the way it handles 
arrays?), so I just adapted it to VBA without bothering to streamline it. In 
any case it doesn't make much sense in VBA for sure. Perhaps the FACTRL 
function can be simplified as well.
When I wrote that, the whole Fisher part seemed to run on pixie dust anyway 
and I was in a hurry. It worked, so I didn't change anything for fear of 
breaking stuff.
