What is the .OPX File Extension?

.OPX File Extension Description:

The Open Programming Language (OPL) is an interpreted language whose implementation takes the form of an interpreter. It is often used on portable devices like mobile telephones and PDAs that run the Symbian Operating System.

To extend the functionalities of OPL, a special mechanism was designed so that the full capabilities of the underlying Symbian OS can be accessed. This mechanism is called OPX, a DLL that contains the functions of C++ but exposed to the interface of OPL. These functions end in OPX file extension.

Each file with the .opx file extension has its own version number, which allows the OPL runtime to check the correct version of the file before it runs an application. If the version is not the same or is lower than the file version used by the programmer when the application was written, a dialog is displayed that tells it is the incorrect version making the application to stop without even running.

* System.opx source code - can be used by developers as working examples to produce files with the .opx file extension.
