I'm using SAS EG 5.1 on Windows 7. I have the following sample input. I wish to order this input in such a way that whenever different observations match on ID and on Time, the final state of a given observation matches the initial state of the next observation. The output should look like this: I'm at a loss on how to do this. Any help? Here's the code that generates the input table. Data Test;
Infile datalines delimiter=',';
Input ID Initial_Stafe $ Final_State $ Time;
Datalines;
