Discover APL

Getting started with any new programming language can seem like a daunting task, and at Dyalog we've done what we can to try to make this process easier for you. The following resources are aimed at APL novices (none of them require you to have Dyalog APL installed):

  • The book Mastering Dyalog APL by Bernard Legrand is a complete guide to the use of Dyalog APL, beginning with a thorough introduction to the APL programming language and progressing to worked examples.
  • The on-line tool TryAPL offers an environment in which to practise simple APL expressions. It includes a tutorial mode (under the Learn tab) in which some specific scenarios are explored.
  • The Dyalog APL Tutor is an on-line system that takes a complete APL novice through the terminology, conventions and functionality of Dyalog APL.
  • The APL Orchard is a StackExchange repository of text-based lessons.

In addition, a complete documentation set is available to download.
