you can try to use pipe to read in if all csv files in last 7 days are the same layout
for example:
filename indata pipe "dir C:\test\*.csv /S";
data vname;
  length fname $50.;
  format fdate mmddyy10.;
  infile indata missover;
  input date $10. time: $8. apm: $4. size: $20. fname: $50.;
  if anydigit(date)=0 then delete;
  fdate=mdy(substr(date,1,2),substr(date,4,2),substr(date,7,4));
  if fdate>=(today()-7);
  keep fname fdate;
run;

data _null_;
    if 0 then set vname nobs=nobs;
    call symput('nvars',nobs);
run;

%put &nvars;
then write a loop to read in all sas data sets

找stat transfer 转成sas自己的格式

学习了，

目前为止的修改器只能适应1.10版本，如果你确实想修改，你就降回1.10版，修改完了以后再升回1.11版。如果你想这样修改，那我倒是能给你修改器。

好办法，谢谢大家的分享。
