Lode, striegel got it right CLP will wipe a flash program as well. To get the code back into the calculator you will need a serial connection between your PC or MAC running one of the emulators. You can then copy the programs from the emulator to the calculator RAM and PSTO into flash. PSTO will always put the code at the end of the library space. That's a restriction imposed by the limited RAM and programming space of the Atmel chip.
