Dear SAS Users,
Hello SAS Users...I have two columns an sample of which is shown below....

ID NUMBER

35 1015
35 1015
35 1015
36 2014
36 2014
41 5689
41 5689
42 5689
56 9878
56 9878
57 9878
62 4512
62 4512
62 4512
68 6398
68 6398
68 6398
69 6398


I want to write a code which will allow me to show "ID" which has same "NUMBER"..

The sample output should be like:

ID NUMBER

42 5689
57 9878
69 6398

Your expertise in this regard would be greatly appreciated. Thanks in advance.
