Open Programming Language

The Open Programming Language (OPL, formerly Organiser Programming Language) is a programming language for the operating system Symbian OS, as it can be found on the Nokia Communicator and other mobile phones. The language was originally developed by Psion Organiser as a Programming Language for the Organiser II (1986 ) and used for other PDAs the company. After Psion withdrew from the PDA market, the project was continued as an open source and reinterpreted the acronym. The language is now being developed by the project on SourceForge opl -dev. There are now Psion Teklogix also a version for the Windows CE operating system.

OPL is based on BASIC. Here's a little hello world program:
