May I take the liberty to inform also on the existence of other free 
languages, although absolutely not fashionable nowadays? I suggest 
SNOBOL and ICON. They were both originally designed by Dr Ralph E. 
Griswold (Arizona). I still prefer the former, but Icon is very much 
preferable to those who are used to the syntax of standard-structured 
languages as C or Pascal. The main field of application of these 
languages is string scanning and parsing, but they can also be used as 
general purpose. One advantage of Icon is that graphics need no 
libraries -- graphics capabilities are internal to the language -- so 
you can easily write a program for Linux and, if you want, compile 
another version for Windows without changing a single line of code.

(1) Snobol
http://people.ne.mediaone.net/philbudne/snobol.html
Here is Phil Budne's <[EMAIL PROTECTED]> free Snobol interpreter, with 
all the extension of Spitbol (a more modern version of the language, not 
running on Linux). See also http://www.snobol4.com/ for Mark Emmer's 
Snobol page.

(2) Icon
http://www.cs.arizona.edu/icon/ is the starting point. See also 
http://www.nmt.edu/tcc/help/lang/icon/ and http://icon.cs.unlv.edu/
Another version, named unicon, is being developed, and in the first page 
listed above you'll find information on a Java porting of this language. 
All of this is obviously free.

I have been using these languages for several purposed, including 
musical analysis, and I find them very useful for my programming needs. 
I am no professional programmer.
