Tip: If w is less than
4, the last two digits of the year print. Otherwise, the year value
prints as four digits.
Details
The YEARw. format is similar to the DTYEARw. format in that they both write date values.
The difference is that YEARw. expects a SAS date value as input, and DTYEARw. expects a datetime value.
Example
The example table uses
the input value of 19158, which is the SAS date value that corresponds
to June 14, 2012.
