Hi, community,

 

I am seeking an automatic way to read all SAS data in a folder to do the same process. 

Thank you so much.

 

Here is my manual code. It works but takes time to key in all filenames. 

/**/

Libname path "C:\myfolder\SAS";
Data &filename;
set path.&filename;
sas statements;

.

.
run;

%let filename=a;

%let filename=b;

............

Thank you. It works like magic.

So every dataset in the library has to be processed using the same statements. I am sure that such tasks have been solved many times - you will find them using the search function.

Here's just a recipe:

  1. Write the step that process one file, have it fully tested.
  2. Convert the step to a macro, a parameter for the dataset is mandatory.
  3. Test the macro.
  4. Write a data step reading sashelp.vtable with where statement to process only the datasets in your library.
  5. use call execute to execute the macro for each dataset found.
