APL - An Educator's Personal View James E. McKenna correction, even in those primitive times before lull screen editors, was also easy. The term "user friendly" had n o t been coined yet, b u t if I had heard it, I would have known at once t h a t it applied to A P L programming. This freedom from excessive concern over syntax errors m e a n t I could spend more time at the s t a r t of s project concentrating on what was to be done. I knew that syntax errors would happen b u t I also knew that there would be an inconsequential cost associted with them. Then, an amazing thing happened. The frequency of syntax errors decreased far more quickly t h a n I expected. It reminded me of the way we were taught French at my high school. We were t a u g h t by total immersion, that is, after the first few weeks of class, we spoke nothing b u t F r e n c h in class. To make it interesting, the teacher fined us five cents for e~ch English word
