Comments
This B_CALL gets the first five bytes of the ID as actual bytes, you have to convert them before you display them. The rest of the ID can't be retrieved using a B_CALL, although there seems to be a call address to get them in every OS. The only problem with using this call address is that your software will only support the OSes you add support for and will never work after an upgrade to a new OS.
