PP is a freeware standard Pascal compiler for PalmOS that runs directly on the handheld. PP generates true native 68000 and ARM executable code from standard Pascal source code. Console applications, standard Palm applications, shared libraries, DA's, armlets may be generated on board in the train, while waiting the bus, while fishing, on the beach, or wherever you are.
An Android version Pépé le compiler is now available. For the moment, it only allows to develop console applications.
