+In Visual Basic 15.8 and earlier versions, comments are only allowed on blank lines, at the end of a statement, or in specific places within a statement where an implicit line continuation is allowed. Starting with Visual Basic 16.0, comments are also allowed after explicit line continuations and within a statement on a line beginning with a space followed by an underscore.
