The first one is 001. Beneath the sequence number are Xs, which you
i0
replace by typing in the response to sequence number 001 (below). If
the response you enter is acceptable, a new sequence number will be
displayed. If the response is unacceptable, a 2-digit operator code will be
displayed in the upper center portion pf the screen. See Figure 5-4 for
the meaning of this code.
If you are using a 3179 display station, it must be operating in 3279-
emulation mode. If you are using a 3180 display station, it must be
operating in 3278-emulation mode. lfyour 3179 or 3180 is not in
emulation mode (that is, if it is in native mode), the number 212 appears
in the operator information area of the display screen when the first key.-
stroke is attempted and customizing cannot proceed.
