A PDF file is not a computer program, it does not execute on the CPU but contains instructions for an interpreter to process to generate the page. That is different to executables (which run directly on a CPU). Most data files are little more than scripts, that are interpreted by a host program.

But you're not right on how programs load data files data is not always a program. But then I think it's too broad to ban all executable code since it covers emulation too. That executed code could be further sandboxed to prevent viruses or malware. I understand why Apple rejects executable code - it could allow app stores within an app for example unless prevented by further guidelines (not saying that's necessarily a bad thing, but thats's likely their angle). Based on the BeOS version of Sweet16, which was in turn based on the. Isn't programs as data and data as programs the basic principle of computing? Sweet16 is the most capable Apple IIgs emulator for computers running Mac OS X. For example, PDF files are themselves computer programs which instruct and iPad how to render a PDF visually. In reality, executing code in an emulator is what programs do. Though not ready for stable usage, it can run Mac OS X 10.3 more or less. PearPC: PearPC is the first free, open source PowerPC Architecture emulator out there, and it seems to have made great progress so far.

It emulates a Macintosh 128K, Macintosh 512k, Macintosh 512ke or a Macintosh Plus. I think Apple's guideline rejecting executing code is needs to be eliminated - an emulator is an emulator. PCE/macplus is a Macintosh Plus emulator.
