[parmesh]

I have csv files saved in my local machine need to delete it using SAS.

I have used the below code but its not working.

%macro abc;
%do i=1 %to #
filename delfile&i. "C:\MBR\CSV\&&nama&i..csv";
data _null_;
rc=fdelete("delfile&i.");
run;
%end;
%mend;
%abc;

I get the below error

ERROR: Invalid logical name.

Your FILEREF delfile&i exceeds the limit of 8 characters when &i reaches 10 in value. Reduce the length by calling it say delfl&i.

Store your filenames in a dataset, and use data step logic in place of the macro code. It's cleaner and performs better:

data files_to_delete;
input fname :$256.;
datalines;
$HOME/test/test1.csv
$HOME/test/test2.csv
;

data _null_;
set files_to_delete;
rc = filename('fdel',fname);
if rc = 0
then do;
  rc = fdelete('fdel');
  if rc then put "delete failed: " fname;
end;
else put "filename failed: " fname;
run;
