//Returns a new date based on the original date plus value IN either OLE
//automation format or as a string formatted date. The interpretation of 
//value is determined by the unit. 

//Possible choices FOR unit are: year, month, week, day, hour, minute, 
//and second. 

//Enclose the unit IN double or single quotes, or pass a variable which 
//contains the unit name. The unit name is CASE sensitive.

//[String expression] Resulting date will be formatted as a standard date/time 
//string: MM/dd/yyyy h:mm.ss AM/PM.

//[Numeric expression] Resulting date will be a floating point value IN OLE
//automation format.

//These are examples of adding to a datetime variable
