Again, PostScript. http://en.wikipedia.org/wiki/PostScript#.22Hello_world.22 http://en.wikipedia.org/wiki/PostScript#.22Hello_world.22

  Postscript is so unpopular to use as a programming language that github doesn't even have it in their languages. I'm not even sure if you're just trolling or serious?

    I can second the use of postscript. A while back, I took it as a challenge to learn it, and ended up making some fairly extensive programs. I've actually found myself wishing there was a popular general-purpose scripting language that closely resembled postscript (stack-based, first class functions, first class environments). You can download the books for it for free (the "blue book" is the tutorial). I highly recommend it, along with the "red book" which is also useful for adding to your general programming language theory.

      You're aware of: http://factorcode.org/ http://factorcode.org/ ? (Popular would be a stretch, I guess)
