/*So for this, you have to create a macro to store the path of the folder where your files are located .*/
/*STEP 1:*/
%let dirname = C:UsersRANAJIDesktopSAS_Class_CodeMultiple_csv_files;
filename DIRLIST pipe "dir /B &dirname*.csv";
data dirlist ;
length fname $256;
infile dirlist length=reclen;
input fname $varying256. reclen ;
run;
proc print data = dirlist;
run;
/* so , once your all files are located there, you can proceed with step 2 */
/* Step2*/
data all_text (drop=fname);
length myfilename $100;
length name $25;
set dirlist;
filepath = "&dirname"||fname;
infile dummy filevar = filepath length=reclen end=done missover;
do while(not done);
myfilename = filepath;
input name $ x1 x2 x3;
output;
end;
run;
proc print data=all_text;
run;
you will have all the files appended in the new dataset.
