Word 1 indicators display the contenn af the L register. The L register is a primary source of
15 RL031
data for odder XG input and buffer for local store. The L register can also gate a byte of
Pl6-23 RL041 data at o time to the mover. Bit positio"s 0, 9, 18, and 27 display the parity of the associ-
16 RL041 ated byte.
