void = IncludeHolidaysList(sChar)
This macro function was used to leave a marker in the compiled code of the macro, indicating that the macro uses one or more of the aeiou-holidays lists. This marker was then used to issue a warning you if these holidays lists are not defined. But, this function is now obsolete and does nothing.
To indicate that a macro uses a aeiou-holidays list, you should use the INCLUDE_HOLIDAYS_LIST compiler directive instead.
