Answer Posted / robertd903
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.
