SAS INTERVIEWS CONCEPTUAL QUESTIONS XVI

We have a SAS Data Set:


                                      One
                      -----------------------------------------
                                  Date_Info
                      -----------------------------------------
                           24Nov is Sunday
                           25Nov is Monday
                           26Nov is Tuesday
                           27Nov is Wednesday
                           28NOV IS THURSDAY
                           29nov is Friday
                           30NOV is SATURDAY

 We need to create A SAS Data SET where only days should be in uppercase and rest should be in lowcase.


                                      One
                   -------------------------------------------
                                  Date_Info
                   -------------------------------------------
                           24nov is SUNDAY
                           25nov is MONDAY
                           26nov is TUESDAY
                           27nov is WEDNESDAY
                           28nov is THURSDAY
                           29nov is FRIDAY

      cats will remove the leading & trailing blks and concatenate them, instead catx with delimiter can be used or cat.
