Answer / yachna

There is only one difference between Scan & Substr..Just look at below example

eg. String = rajesh chauhan
   If we want first four letter of the string then we can use Substr function here not scan..Scan function can pick first word.
  SubName=Substr(String,1,4);
  ScanName=Scan(String,1,' ');

      Subname = raje
      ScanName=rajesh
