About this guide...

This is the Programmer's Guide for ioL.

Assumed knowledge

This guide won't teach you how to program from scratch. It is assumed that you already know how to write simple programs in a language such as Python (or another programming language that may also be available in your version of Proxima).

This guide focuses on an essential aspect of programming - dealing with input and output - which Proxima's VUI (Versatile User Interface) system manages in a different way to other operating systems. It will teach you how to make your program deal with input and output in a way that takes full advantage of the capabilities provided by ioL and Proxima's VUI system.

How the guides are structured

• The Programmer's Guide introduces basic concepts chapter by chapter, eventually moving on to more advanced practices.
• Once you grasp the basics, the Language Reference is where you can look up various tags (objects and functions) available in ioL and how to use them.
