Programming Languages

The question around the office was "How many programming languages do you know?"
We used the metric of "have written 'Hello World'" - so that's not really "know" but rather, have seen. We also excluded "versions" of languages. I also excluded languages that I have edited / fixed something in but didn't really program anything, not even "Hello World". My list, posterity, in the best memory of chronological order:

1. BASIC*
   I started in BASIC on a CP/M machine, then moved to GW-BASIC (I still have some of these programs - haven't tried running them) with my first paid program, later to QBASIC and QuickBASIC and then Visual BASIC - also did some Apple BASIC.
   
2. Logo
   On several Apple ][s, naturally.
   
3. Pascal
   Middle school & high school classes.
    
4. Assembly
   My hello world was a program that showed some fireworks on the computer - got some help from an old BYTE magazine.
   
5. IEF*
   A CASE tool. Apparently its ancestor still sells (2007) from CA.
   
   
6. C++
   Couldn't be a university programming 101 course without it.
    
7. VBScript*
   Also counting VBA* in here - shudder
   
8. Javascript*
   Also counting Flash Actionscript* in here. Start in Flash 4 and so got another taste of "clicking in" code - which is frustrating for one who can type fairly quickly.
   
9. SQL*
   Specifically T-SQL, but also variations for JET and SQLite - probably even tweaked a script for MySQL at some point.
   
10. C#*
    
11. Java*
    
12. Lisp
    
13. ? Python
    I think I tinkered with this on my OLPC - maybe SCHEME / Squeak, but I don't recall for sure, so I don't count this one.

Forthcoming Ruby on Rails this fall. Hopefully eventually Clojure will get on this list.
