McAleely.com -> EPOC -> OPX List List Updated: July 2001

Search | Site Map

This page is intended as a resource for EPOC OPL developers. It is a list of all the language extensions, known as OPX's, that I am currently aware of. I only list here currently shipping OPXs - some older and obsolete extensions are no longer listed. If you are writing the next version of an application - check with the provider of any OPXs you use for updated versions. Some early OPXs had important installation problems ('version safety') that can be avoided with their latest incarnations. These early problems prompted me to write an article for users installing OPX's, and one targeted more at developers. Both are a little dated now!

If you want to know more about EPOC programming and what an OPX is, try 3Lib, or the Symbian Developer Network.
