I have about 10 experience with SAS and am currently working through the exersices in "Learning Perl." SAS is no longer, from a revenue standpoint, a "Statistical" package. The "data base" part is huge and SAS is alway trying to get their fingers into every pie (including hosting). They do a very good job. Their people are top notch.
If I knew as much PERL as I know SAS, I would use PERL for the web not SAS because PERL is a programming language and is supported by the top minds in web programming.
