Passing by reference, is passing the ADDRESS of a variable--to a subprogram. The subprogram is able to change the value contained in the variable.

Passing by content is passing the DATA contained within a variable--to a subprogram. The subprogram can NOT change the value of the data in the (calling program's) variable.

I need to compare 3 variables(dates) and do some processing based on the earliest date. There could be more then 1 date record in any of the 3 fields. What is the best way to code this?
