Can I use 0x80 as my CLA value? ISO/IEC 7816-4 spec states that for this CLA, the command coding and meaning is proprietary. Does that mean it is proprietary to my code? And I don't have any question with using this value, so it indicated that this value is legal, right?

This is fine. It just means you need to document each of your commands you support. If you used ISO/IEC 7816-4 commands, you could just say what commands you support.

Thanks for the quick reply.
I have another question. ISO/IES 7816-4 says that 0x20 - 0x3f are reserved for future use. Does that mean I should not use these CLAs? Right ?
