E.g. if the application directly stores a byte into `#ffff`, the runtime may consider it writing to the `07` control port and process it as a system call. For now, this rule is not enforced and `DEO`/`DEI` instructions are the main source of truth when interacting with control block, but this can (and most likely will) change in the future specification versions. ## Screen output
