Hello, My colleague just created SAS data file for me and left his office. My problem is that I could not open (or use) his data in my sas code. The ERROR says that the file does not exist, even though it exists. Last time I had the same problem, I ran his format statements that were copied from his sas code used for creating the data file before I read in it. It worked out well that time. But this time, it does not help at all. Do I have to see something else? I use Linux-based SAS. Thank you in advance, Duckhye
