Resources to help you take your first APL steps – there are also some tips that should make the process a bit easier:

  • Mastering Dyalog APL by Bernard Legrand is a complete guide to the use of Dyalog, beginning with a thorough introduction to the APL programming language and progressing to worked examples. The book is available for purchase through Amazon; a free PDF download and an online revision (currently under development) are also available.
  • TryAPL offers an interactive environment that allows users to play with simple APL expressions. Its Learn tab includes tutorials in which various scenarios are explored.
  • APL Wiki includes simple examples of APL in action (as well as some more advanced ones).
  • APL Cultivation is a series of chat lessons that were run through the APL Orchard chat room.
  • APL Course is a self-study introduction to Dyalog with exercises.
  • APL Tutor is an online system that takes a complete novice through the terminology, conventions and functionality of APL (not specific to Dyalog's dialect) – it looks a little dated but is a useful introduction.
