My Psion Pages

Programmer's Toolbox

This library of OPL procedures is what I use to develop software on the SIBO series of computers. It provides a complete event-driven framework for you to develop your applications around. It's big feature is asynchronous menus and dialog boxes - your application can do serial comms, play WVE files or other background processing while the user is simultaneously working with menus, dialog boxes and help windows. There are too many features to list here - see its main page for full information.

Developments in the SIBO Programming Scene

While I don't actively search out news and developments, anything interesting I do hear I'll list below:

• 2002-03-10: Psion Teklogix have released the OVAL SDK for free. Go to their web site, click on "Partner Program" and login. You'll have to register (it's free) if you haven't already. Then click on "OVAL SDK" and download the two disks and manual.
• 1999-08-15: Complementing Christophe Amrein-Marie's Psion C Project is Borland's old Turbo C v2.01 compiler, recently released on the Borland Community Museum. If the documentation-only version of the C SDK didn't cost so much (AUD$650) I'd try these out.
