 Use the 
		  IntDictionary type to map string values to integer
		  values. This example shows how to map the names of weekdays to numbers: 
		
int DayOfWeek(string name)
{
	IntDictionary weekDays = CreateIntDictionary();
	weekDays["mon"] = 1;
	weekDays["tue"] = 2;
	weekDays["wed"] = 3;
	weekDays["thu"] = 4;
	weekDays["fri"] = 5;
	weekDays["sat"] = 6;
	weekDays["sun"] = 7;
	return weekDays[ToLower(name)];
}
