APL's terseness means that substantial programs are expressible in a small space, relative to many other programming languages. Below are just a taste. Many more, and fully explained, examples are in the [[simple examples]] article. | APL's terseness means that substantial programs are expressible in a small space, relative to many other programming languages.
