SAS Tip of the Month
September 2015
(for SAS)

How can an external file be deleted using SAS? One way is to use the 'X' command and use a system command like 'DEL' in DOS. But another way is to use the FDELETE function inside a datastep as the following example demonstrates:

   data _null_;

      ** Assign the external file being deleted to a
         reference 'fn' using the FILENAME statement;

      ** Now delete the file using the FDELETE
         statement -- if RC does not equal zero then
         there is an issue;
      if rc=0 then put "File deleted";
      else put "ERR" 
             "OR: Issue with trying to delete the file";

      ** Clear the FILENAME reference 'fn';


In the example the dataset DMEXT.TXT in the directory C:\TEMP is deleted -- there is also an additional piece of code that puts out a message as to whether there is an issue with the deleting of the file or not.

Hope this was useful.
