Thanks Kilgoretrout. I didn't find references to SalStat when I googled nor when I went through freshmeat. I am very appreciative of your help. I have also had a brief flurry of communication with one of the PSPP developers who has been quite helpful, so I am hoping that I'll be able to compare PSPP and SalStat soon.
I did download and install ViSta, but Professor Young obviously has not spent much time figuring out how to port ViSta to Linux, or he hasn't had too much support, which is a pity because I used to like using ViSta.
Once again, thanks.
