How to automate and import files that are located in date sequential folders into SAS?

Question

I currently have 700 folders that are all sequentially named.

The naming convention of the folders are as follows:-

2011-08-15_2011-08-15    
2011-08-16         


        

Answer 1

You should be able to wildcard the folders/files into a single fileref, e.g.

filename allfiles "c:\SAS_data\extract\*\*.txt" ;

data alldata ;
  length fn _fn $256. ;
  infile allfiles lrecl=256 truncover filename=_fn ;
  fn = _fn ; /* Store the filename */
  input ;
  put _INFILE_ ;
run ;

The wildcard folder & file works in SAS Unix, not sure about SAS PC.
