This programming example was produced in response to a social media post about an earlier simple OPL program. "At last something for those of us that don't have cables and connections that can be typed in at the keyboard". Thus this suite of programmes were designed to be an introduction to programming, are deliberately short to type in at the keyboard and be able to be run on any PSION device that can edit and run OPL. Combined they form a simple petrol/diesel fuel logger.
For those without the inclination to type in the OPL programs contained in the instructions below they are all contained in this ZIP archive (here)
