Subject:      Data step stops processing if no observations read from where
Content-Type: text/plain; charset=ISO-8859-1

There is no x=2 in the master dataset, but I still want it to append
data to the bottom of the dataset (and I want it to append data to the
bottom of the dataset in the case that there was x=2).  Any ideas?

Thanks,
Sterling

20         data master_append;
21
22             put "BEFORE: " _ALL_;
23             set master;
24             where x = 2;
25             put "AFTER: " _ALL_;
26
27             do i = 1 to 5;
28                 output;
29             end;
30         run;

BEFORE: x=. i=. _ERROR_=0 _N_=1
NOTE: There were 0 observations read from the data set WORK.MASTER.
      WHERE x=2;
