Answer 1

Answer:

The three parameter modes, IN (the default), OUT , and IN OUT , can be used with any subprogram. However, avoid using the OUT and IN OUT modes with functions. The purpose of a function is to take no arguments and return a single value. It is poor programming practice to have a function return multiple values.
