Revision control for SPSS source code

[Bridgette Portman]

Hi all,

I'm using version 19 for the Mac -- the problem could be there, rather
than something in 19 for windows. The other problem I have is Fisher's
Exact always comes out 1.00.

Thanks for helping me figure this out. I'm troubled that there's a bug in
the program, but glad the problem isn't in my data, or I'm insane...

Bridgette

p.s. Bruce, you asked why age categories and not age...my age wasn't
normally distributed; it was bimodal, where I had a lot of young people
and a lot of older people, so I thought it best to just split it.
