  Sample input:
NextDayNameDate ( theDate; "Monday" )
  Sample output:
09/26/2005
if theDate is 09/25/2005

  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

returns the date with the first occurrence of theDayName from the given theDate;
if the given theDayName is the name of the day of the given theDate, it returns theDate.
So, if we wish to know what is the date of the next Monday from theDate 09/26/2005 we can write:
Case(
theDate = "";"";
NextDayNameDate ( theDate; "Monday" ) = theDate ; NextDayNameDate ( theDay; "Monday" ) + 7;
NextDayNameDate ( theDay; "Monday" )
)
and it returns: 10/03/2005
