如题
SAS中file和infile用法的区别

data _null_;
set work.addresses;
[ file "c:\email.sas";]
put "filename mail email ' "Email_Address" ';";
put "data _null_;";
put" put 'Thank you for your continued'; ";
put" put 'support of the XYZ corporation'; ";
put" put 'We appreciate your patronage'; ";
put" put 'Sincerely'; ";
put" put 'The XYZ Corporation'; ";
put"run;";
run;


为何[]要用 file "c:\email.sas";而不是 infile "c:\email.sas";




谢谢
