I'm sure there's a simple solution to this problem, but I'm a new enough user so here goes. I'm using SAS enterprise guide. I have a dataset like so   var1 date 1.1  Feb2018 1.4  Mar2018 2.6  Apr2018 3.3  May2018 4.5  Jun2018   and I would like to create a column that repeats the earliest var1 value, like so   var1 date    base 1.1  Feb2018 1.1 1.4  Mar2018 1.1 2.6  Apr2018 1.1 3.3  May2018 1.1 4.5  Jun2018 1.1   Not sure if I should use proc sql or a data step here. Thanks in advance ... View more
