Course if you dropped the APL ball,

Gosh, the APL ball.  That brings back memories.

For you newbies, he is referring to the IBM Selectric Typewriter, which had a replaceable ball with all the characters on it, depending on what special character set you wanted. Selectrics were also used as interactive terminals. APL uses a lot of arcane characters, so you needed a special Selectric ball and key tops to program in APL, or read the code. Selectrics were fun to watch when typing fast. The ball would spin and tilt just like those gut-spewing rides at traveling carnivals.

Neat language, too. Back at Brown University in the early 70s, I worked with OS and CP/67 and CMS, but I learned APL and as an exercise I wrote the equivalent of the CMS file editor in a half-page of APL code (of course the CMS editor of the time was a simple line-oriented editor)
