If you do not include one of the access keywords, a function will be Public by default. Any number of ExitFunction statements can be placed within the function. Execution will continue with the line of code immediately following the call to the function. If a value has not been assigned to the function when the ExitFunction statement executes, the function will return the default initialization value of the data type specified for the return value of the function.

To return arrays of any type from a procedure, you must use parentheses after the data type in the return value of the function declaration, as in: Public Function Test() As Integer( )
