data _null_; length data $1; INFILE in_filename recfm=n; file out_filenmae recfm=n mod; input data $char1. @@; put data $char1. @@; run;
Although this is written for STP web process it should apply when writting to another file as the _webout is similar. The secret seems to be the recfm=n and the @@s.
