specifies the width of the output field.
The YYWEEKVw. format writes
the various formats depending on the specified width. Algorithm V calculates
the SAS date value, with the number-of-the-week value represented as a decimal
number in the range 01-53, with a leading zero and maximum value of
53. Weeks begin on a Monday and week 1 of the year is the week that includes
both January 4th and the first Thursday of the year. If the first Monday of
January is the 2nd, 3rd, or 4th, the preceding days are part of the last week
of the preceding year. For example, the fifth week of the year would be represented
as 06.

The YYWEEKVw. format is similar
to the WEEKVw. format except that the YYWEEKVw. format does not specify the day-of-week information. Also,
the YYWEEKVw. format does not accept a width
that is greater than 8.
