Paste an Arbitrary Piece of Code

If your working on some code… just randomly copy a piece of it and paste it in the comments… This code is from a program that generates any major scale (it’s still not finished). Feel free to post code chunks in any language…

[EDIT] the code doesn’t need to work on its own… you can just randomly copy from something your working on…
