GeneveOS makes frequent use of XOPs and offers them for user programs.

			The XOP instruction takes two arguments; the first delivers data for the call, the second is a number from 0 to 15 and indicates the '''XOP number'''. In GeneveOS, all system calls are XOP 0 with specific arguments:

	ARGUM DATA <number>		ARGUM DATA <number>
