Hi everybody! I am new here, I am a doctor and I use SAS to perform basic stat analysis. Right now I am having trouble editing a dataset, I am not sure how to solve the problem but I know there must be an easy way to do it, so I am asking for your help This is a sample of my dataset id      exam1      exam2    exam3        exam4 1       1999        2007      2003          2000 2       2009        1985      2004          2001  3       2000        2001      2002          2003 What I want to do: to create a new variable 'firstexam' in which i have the name of the first exam and not the actual date my new dataset should be like this: id   ...   firstexam 1          exam1 2          exam2 3          exam1 if i use the min function I get id   ...    firstexam 1             1999 2             1985 3             2000 I know I could do it with a bunch of 'if' and 'then' but the editor would be so long and ugly.. I am sure there is an easier way to get the job done... Thanks a lot! ... View more
