Answer 2

A Function procedure is a series of Visual Basic statements enclosed by the Function and End Functionstatements. The Function procedure performs a task and then returns control to the calling code. When it returns control, it also returns a value to the calling code.

Each time the procedure is called, its statements run, starting with the first executable statement after the Functionstatement and ending with the first End Function, Exit Function, or Return statement encountered.

You can define a Function procedure in a module, class, or structure. It is Public by default, which means you can call it from anywhere in your application that has access to the module, class, or structure in which you defined it.

A Function procedure can take arguments, such as constants, variables, or expressions, which are passed to it by the calling code.
