Leap Year and the Day of the Week
Leap year is displayed as a number representing the number of years since
the last leap year. For example:
–[GET]–[GET]–
00A
00B
In the first Get:
000 represents leap year
001 represents the first year since leap year
002 represents the second year since leap year
003 represents the third year since leap year
In the second Get, the day of the week is displayed as a number from 1-7.
You may set this Get to any number from 1-7. It increments each day at
midnight. After it increments to 7, it starts over again at 1.
Word format for set and read leap year and the day of the week functions
are the same. The only difference between the two EAFs is their function
number: set leap year and the day of the week is 12; read is 17.
Enter EAF rungs like those shown in Figure 16.17.
