I have some data with 500 records. I need to sum the numbers of the duplicate record. I did it using PROC SQL, but it change the order of the records at output. Can anyone suggest me how PROC SQL plays with records. Also if i want to keep the original order of the records, how can i do it. Thanks in advance. Example Var1 Var2 Var3 100 135 ase 123 143 ase 124 53 per 400 250 fge 100 300 fge What i need is: Var1 Var2 Var3 223 278 ase 124 53 per 500 550 fge
