使用分隔符打印所有列 SAS

Question

我正在尝试打印一个分隔文件，而不必指定所有列。我可以接近，但数字列总是被引用：

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"

我怎样才能实现：

"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

或：

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

Answer 1

~ 要求引用。所以，你正在引用。

您可以改用&：

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

& 实际上对数据没有影响（我们曾经有过一个关于它的问题，我不记得最终的答案，但基本上它似乎主要用于这个特定目的，甚至虽然这不是它的目的）。
