No, you are missing the point. Take a page full of intense mathematical notation or an orchestral score and translate it into either full words (i.e.: "integral" in place of the integral symbol) or one, two or three character ASCII mnemonics. You should realize that the original is far more powerful a tool for communicating thoughts, ideas and the subject at hand than a seemingly random dump of ASCII on paper.
You did mention that you did not bother to learn APL. That's the reason you don't get it. I am trying to use mathematical and musical notation to illustrate the value of notation. It is obvious I am not doing a good job.
Let's just disagree and move on.
