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.
