I know (fluently, though need to brush a little rust off).
C++, Java, Pascal, SQL and HTML.
I know some, and could easily become fluent in BASIC, Quick BASIC, C, C#, ASP, PHP, VB
Familiarity, but really would need to do a lot of learning to use it, Assembly, Pearl and FORTRAN
I prefer C++, its tried, true and I am intimately familar with it (okay, a couple of years rusty, but I've put at least 5 or 6 good years of learning and use into C++ compared with no more then 2-3 years of good use out of any other language).
