; we have to call `brk` to trigger the interrupt
; in any of the three registers we can have arguments
; or we could have them pushed to the stack, assuming
; the stack is in the same location
; Or you could pass a pointer which points to an array
; of arguments
; for things like clear, read/write character, and init you don't
; need any arguments.
