APL has been around for decades, and it's still a popular tool for software development. Users love it because of its simple, terse syntax and its rich set of built-in functions.

Today the most widely used implementation is Dyalog APL.

You can run a free version of Dyalog APL on all the members of the Raspberry Pi family, including the new £4/$5 dollar Raspberry Pi zero.

You can also run free personal versions of Dyalog APL on Windows, other Linux computers, and Mac OS/X.

This introductory book has plenty of examples and code for you to try out. Written by an expert APL developer and instructor, it will give you a gentle introduction to one of the most powerful languages ever created.

If you're interested in scientific, financial or big data applications, APL's mathematical capabilities will help you build working code quickly. APL's lightning-fast array handling lets you build software that runs fast, too.

You can even take advantage of multiple CPU cores and write programs that share their work between multple networked computers.

You should read this book if you want to

find out what programming in APL is like
learn how to use the language effectively
decide if APL is appropriate for your project
take part in the Dyalog annual APL problem-solving competition

Dyalog APL comes with the SharpPlot package, and you'll learn how to create beautiful graphs to persent the reults of your calculations. Once you've worked through this introduction you can download other free materials to help you complete your mastery of APL.
