Functions can return values using two different syntaxes. The modern, and correct, way to do it is to use a ``++Return++`` statement. The VB6 way, i.e. old way, is to assign a return value to the function's name .


The VB6 syntax is obsolete as it was introduced to simplify migration from VB6 projects. The compiler will create a local variable which is implicitly returned when execution exits the function's scope.


``++Return++`` statement should be used instead as they are easier to read and understand.


== Noncompliant Code Example

----
Public Function FunctionName() As Integer
    FunctionName = 42 ' Noncompliant
End Function

Public Function FunctionNameFromVariable() As Integer
    Dim Value As Integer = 42
    FunctionNameFromVariable = Value ' Noncompliant
End Function
----


== Compliant Solution

----
Public Function FunctionName() As Integer
    Return 42
End Function

Public Function FunctionNameFromVariable() As Integer
    Dim Value As Integer = 42
    Return Value
End Function
----
