Holiday
Holiday header. The four holiday types with their priorities are as follows:
SPEC (special) - highest priority
DATE (month/date) - 2nd highest priority
D/WK (day of week) - 3rd highest priority
SPAN (duration) - lowest priority
To demonstrate the use of priorities assume that Thanksgiving Break (SPEC) is pro-
grammed as a holiday schedule B. Also assume that Nov. 1st to Nov. 30th (SPAN) is pro-
grammed as a holiday schedule A. Then on Thanksgiving Day and the Friday after, the
control will execute the events that include HOLIDAY B in their day field since SPEC is a
higher priority than SPAN. For the rest of November the control will use events that
include HOLIDAY A in their day fields. The other 11 months (assuming no other holidays)
will be controlled according to the events programmed for the normal days (SUN - SAT).
