But I am not familiar.<BR /> It looks like that there is far too much things to learn in SAS.Althought spend your whole life ,it also can not learn it over.<BR /> <BR /> Ksharp Mon, 17 Jan 2011 02:43:19 GMT https://communities.sas.com/t5/Statistical-Procedures/Apply-growth-rate-forwards-and-backwards/m-p/61658#M2887 Ksharp 2011-01-17T02:43:19Z
