A lot of you (and me, too) learned programming in school with either Turbo Pascal or BASIC. Some with both languages. Despite the rise of object oriented programming, BASIC has still a strong community, especially around Visual Basic from Microsoft (which is object oriented, if you like) and the two dialects DarkBasic and BlitzBasic.
A few month ago, Blitzbasic released a new IDE, called "BlitzMax" which works on Windows, Linux and Mac OS X. Quite cool.
I took a look at the trial version and the IDE comes in a simple looking editor and a few helper tools around that. But the language itself is very easy to handle and if you just want to author something simple, a good choice to release tools and games on 3 platforms at once.
More info can be found on the Blitz Basic Homepage. The trial version is valid for 30 days and you can try it out on all three platforms.
