I think you miss completely the point.
Using subroutines is not going to help you make the code shorter, more compact,
or less repetitious (which is not) in a case like this:

          switch (what_to_do) {
                    case FIVE_THINGS:
                            <statementA>;
                    case FOUR_THINGS:
                            <statementB>;
                    case THREE_THINGS:
                            <statementC>;
                    case TWO_THINGS:
                            <statementD>;
                    case ONE_THING:
                            <statementE>;
                    case NOTHING:
                            break;
          }
