My Question when I am calling the %sleep(SourcePath=&sourcepath) after execution of sleep function then from the 2nd time rc is not equal 0 so its showing  NO success.

My question is why from the 2nd time is showing no success.?

Sorry, but your code is hardly readable. Please use "insert sas code" (running man icon) and past properly formatted code.

[ANIRBAN2]

I have paste the code with the logs I hope it is readable now.
My problem is when code is calling the macro again and again from 2nd time Rc is comming NOT success.
THIS CODE WILL SEARCH A FOLDER IF ANY FILE IS PRESENT IN A FOLDER OR NOT, IFNOT THEN RUN THE PROGRAM AFTER 10SEC GAIN AND AGAIN.
IF ANY FILE FOUND THEN IMPORT THE CSV FILES.

Please describe in plain language what your macro is supposed to do.

You do not need a recursion, a simple %DO loop will do it:

%macro sleep(sourcepath=);
%local rc did count numfiles name; /* local to avoid side effects */
filename ___dir "&sourcepath.";
%let did = %sysfunc(dopen(___dir));
%if &did. = 0
%then %put Error opening directory;
%else %do;
  %let count = 0;
  %let numfiles = %sysfunc(dnum(&did.));
  %do %while (&count. le 3 and &numfiles. = 0);
    %let count = %eval(&count. + 1);
    %let numfiles = %sysfunc(dnum(&did.));
    %let rc = %sysfunc(sleep(10,1));
  %end;
  %if &numfile. gt 0
  %then %do i = 1 %to &numfiles.;
    %let name = %sysfunc(dread(&did.,&i.));
    proc import
      datafile="&sourcepath./&name."
      out=work.ds&i.
      dbms=csv
      replace
    ;
    run;
  %end;
  %else %put No files found;
  %let rc = %sysfunc(dclose(&did.)); /* always clean up */
%end;
%else %put Cannot open directory;
filename ___dir clear;
%mend;

I added a count to prevent infinite looping if the directory is never populated.

Checking the return code of a FILENAME function is not necessary, as the function will always work (even if a file/directory does not exist, the fileref could be used to create it), so I used FILENAME statements.

Cleaning up file/directory handles is necessary as they will accumulate otherwise.

THIS I COULD UNDERSTAND
THANKS.
BUT PLEASE CAN U IDENTIFY THE ERROR IN MY CODE

[Kurt_Bremser]

I guess the culprit is your %GLOBAL statement, and it is not only not necessary, but dangerous. Use %LOCAL instead.

Why? A variable defined as local to a macro will appear as global for all macros that are called from this macro anyway. By using %GLOBAL, you force the called macro to use the variable it inherited through the call, and it then manipulates a value that should have been kept as-is for the "outer" macro.

All good macros take care to define all variables as local, unless an explicit side-effect is wanted, or the variables' contents are never changed in the macro.
