Logic Error              It happens when we get incorrect results after executing the program
                         because of the wrong formulating arithmetic or logic expressions.

                         errors are discovered while running the program, Ex; when declaring a

                        variable of type Byte and during the program running, a value less
Runtime Error than (0) or greater than (255) is entered, so an error appears during

                         the run, meaning that the value is out of range.

&                        Concatenation Operator; it is used to join or concatenate two sting
                         variables.

        Specify the Scope of Declaration for Variables and Constants

Local                    When declaring a Variable or Constant in an Event procedure it can’t
                         be used out of scope of the event procedure

Global                   When declaring a Variable or Constant on the level of the public
                         (Class), So we don’t need the declaration process at each scope of the

                         Event procedure.
