Subject:      Re: Function to select one record in each of multiple subsets of
              records

Theodore,

Like the example, below, I think that a sort with nodupkey will accomplish your task.

Art data one; infile cards truncover ; input ID BeginDate mmddyy10. EndDate mmddyy10.; DateRange = range(BeginDate,EndDate); cards; 1 11/25/1997 01/21/1999 2 12/16/2000 12/20/2001 3 02/21/2000 02/21/2002 4 12/10/1999 12/10/2000 2 10/14/1955 01/12/1998 2 01/01/2002 11/22/2003 3 02/21/1956 02/20/2000 ; run; proc sort data=one out=two; by id descending DateRange; run; proc sort data=two out=three nodupkey; by id; run; ------- "Theodore" <tsmonk@eudoramail.com> wrote in message news:3FBF84BE.7000206@eudoramail.com... > Hello! > Does anyone know of a way to compare valuss in a specified field among > a subset of records and write to a new file only one record that > satisfies a given criterion (e.g. the longest job duration, among > multiple jobs held by one respondent), and then repeat the process over > a very large number of subsets (e.g. respondents in my example above -- > the has records for jobs held by respondents)?
