Taking up a new programming language can be a daunting task. While it can appear cryptic at first, you can learn to [[semantic density|read]], write and [[mnemonics|remember]] APL with little effort. There is plenty of material to help you in the process. | Taking up a new programming language can be a daunting task.

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.
