                     Concatenation Operator
                     You can use the concatenation operator (&) to join  use the + operator for concatenating strings, but for
                     together two or more strings. For example, ap & ple  consistency purposes you should always use the &
                     creates a new string, apple. VBA also enables you to   operator with strings.

                     Comparison Operators
                     You use comparison operators between two        If you compare two string expressions, Excel looks at
                     expressions to determine if the expressions are equal,  the characters in the string and not the string length. For
                     greater than, or less than each other.          example, if you compare abcd with cd, cd is
                                                                     considered to be greater because the letter C comes
                     VBA uses these operators to compare numerical or  after A. This is true even though cd has fewer
                     string values. If comparison operators compare a  characters.
                     numerical and string value, Excel always evaluates the
                     numeric expression as less than the string expression.  The following table lists comparison operators:

                      OPERATOR             PURPOSE

                      =                    Determines if the expressions are equal.
                      >                    Determines if the first expression is greater than the second expression.
                      <                    Determines if the first expression is less than the second expression.
                      <>                   Determines if the expressions are not equal.
                      >=                   Determines if the first expression is greater than or equal to the second expression.
                      <=                   Determines if the first expression is less than or equal to the second expression.
