sas - すべての列 SAS を区切り文字で出力

Question

すべての列を指定せずに、区切りファイルを印刷しようとしています。私は近づくことができますが、数値列は常に引用符で囲まれています:

DATA _NULL_;
  SET SASHELP.CARS (obs = 5 keep = Make Model EngineSize);
  FILE "foo.csv" DSD DLM=",";
  PUT (_all_) (~);
RUN;

foo.csv

"Acura","MDX","3.5"
"Acura","RSX Type S 2dr","2"
"Acura","TSX 4dr","2.4"
"Acura","TL 4dr","3.2"
"Acura","3.5 RL 4dr","3.5"

次のいずれかを達成するにはどうすればよいですか。

"Acura","MDX",3.5
"Acura","RSX Type S 2dr",2
"Acura","TSX 4dr",2.4
"Acura","TL 4dr",3.2
"Acura","3.5 RL 4dr",3.5

また：

Acura,MDX,3.5
Acura,RSX Type S 2dr,2
Acura,TSX 4dr,2.4
Acura,TL 4dr,3.2
Acura,3.5 RL 4dr,3.5
