 Hello:


I have the sample dataset list below.  I would like to remove the duplicates of "Group" of (100, 200, 300 and 400) if I could find the
same text in the subgroup of 101-199, 201-299, 301-399 or 401-499.   Please help.   Thanks.

Please use the code editor to include your code in posts. Otherwise it gets garbled or adds in invisible characters when you try and paste it into SAS Studio.
