==Use==
Originally designed for use on their classic [[Psion (company)|Psion]] PDAs such as the [[Psion Series 3|Series 3]], [[Psion Series 5|5/5mx]], [[Psion Series 7|Series 7]], and [[Psion netBook|netBook]]–netPad, and the Psion produced [[Ericsson MC218|MC218]], OPL was provided as part of the standard application suite. It can also be installed on the [[Nokia]] 9200, [[Nokia 9300|9300]] and [[Nokia 9500|9500]] Communicator series [[mobile telephone]] and [[personal digital assistant]] (PDA) and the [[Sony Ericsson]] [[Sony Ericsson P800|P800]], [[Sony Ericsson P900|P900]], [[Sony Ericsson P910|P910]] series. OPL is also included in Psion Teklogix industrial handhelds such as the Workabout mx, and it also appeared in the lesser known Oregon 'Osaris' organiser, a broadly compatible EPOC32 device that uniquely used version 4 of the OS. OPL is an [[interpreted language]] similar to [[BASIC]]. A fully [[Visual Basic]]-compatible language OVAL has also been developed.
