Lets have a go at programming the PSION Organiser II - Hello World and Mastermind type game. Everything you need is outlined in the Instructions (Introduction to Programming)
PsionProg.pdfThese are the routines used for the Mastermind game example in the Introduction to Programming paper above. As explained on page 4 you can cut and paste these routines into Windows Notepad in order to load them into the ORG2 emulator.
