When the WEEKUw. informat reads a missing value, the value of the YEARCUTOFF= system option is returned as the value.

The expected behavior is a result of a missing value and a note alerting the programmer of invalid data.

* For software releases that are not yet generally available, the Fixed Release is the software release in which the problem is planned to be fixed.

The WEEKUw. informat reads the format of the number-of-week within the year, and then returns a SAS date value by using the U algorithm. The second value is missing and instead of returning a missing value in the output, the value of YEARCUTOFF (1920) is output.
