bool = HolidayOfListOnDate(sHolList, nDate)
This macro function returns true if there is a holiday or one-time-date for the Holidays List sHolList on the date of nDate. Otherwise it return false. The allowed values for sHolList are : 'a', 'e', 'i', 'o', 'u'.
This function is useful if you only want to know that there is at least one holiday occurence on a given date (to change its color for example), but do not care what the holiday's name is.
Note that the code :
bIsHol = HolidayOfListOnDate('a', n_TokenDate)
is the same as
sCurHol = EvalToken(n_TokenDate, '[fa]')
bIsHol = (sCurHol <> '')
but using HolidayOfListOnDate is much faster and should always be used, if you do not need to know the details of a given day's holidays.
