» About the Programmer’s Reference Manuals

The Programmer’s Reference Manuals (PRMs) have been written to provide information on the inner working of the RISC OS operating system. With this information you will be able to understand and develop programs that run on RISC OS.

The complete PRMs are not yet available online, though the task of adding to them is ongoing. All documentation is editable, and information on how to add or edit content can be found here. Feedback and discussion on the PRMs is welcome. The preferred method to use the General Forum. You will need to register an account at this website (free to do so) before you are able to post.
