!RIS homes cursor
PUSH "\e[5;5H"
  ?cursor = 4,4
WANTSTATE +m
PUSH "\ec"
  ?cursor = 0,0
WANTSTATE -m

!RIS cancels scrolling region
PUSH "\e[5;10r"
WANTSTATE +s
PUSH "\ec\e[25H\n"
  scrollrect 0..25,0..80 => +1,+0
WANTSTATE -s

!RIS erases screen
PUSH "ABCDE"

PUSH "\ec"
  erase 0..25,0..80
WANTSTATE -e

!RIS clears tabstops
