%macro anyObs (data);

  %* data - name of data set to check if there are any observations;

  %*  0 if no observations found in data;
  %*  1 if any observations found in data;
  %* -1 if an error occurred;

  %* Note: if option NOTES is on and the data has a where clause
  %*       that returns no rows, then there will be a note in the log
  %*       NOTE: No observations were selected from data set <LIB>.<MEM>.
  %*       There is currently no way to circumvent this.

  %local dsid any ;

  %let dsid = %sysfunc (open (&DATA));
  %if &dsid %then %do;
    %let any = %sysfunc (attrn (&dsid, ANY));
    %let dsid = %sysfunc (close (&dsid));
  %else %do;

%mend anyObs;
