The HOLISTART, HOLIVAR, and HOLIDUR statements specify the variables
in the holidays data set that contain the start date, name, and duration of
each holiday, respectively. When you use a holidays data set, HOLISTART is
required. Because at least one holiday lasts more than one day, HOLIDUR is
required.
