Hi,

I am new to SAS very much appreciated from your reply. My client gave me a txt file which look like the file I have attached, I would like to know how use SAS to capture valid data or skip unessary rows from the raw files and replace those empty column such as date and area.

OK.

filename x  'c:\temp\query1.txt';
data x;
 infile x  expandtabs  pad ;
 input @;
 if left(_infile_) in: ('FIles' 'Date' '======') or missing(_infile_) then delete;
  else  input date $ 8-16 area $ 22-28 id $ 31-39 type $ 40-44 country $ 47-65;
run;
data want;
 set x;
 retain _d _a '            ';
 if not missing(date) then _d=date;
 if not missing(area) then _a=area;
 date=coalescec(date,_d);
 area=coalescec(area,_a);
