I've test Jim's solution but i got one more obserwation in output data:

417  data a;
418  i=1;output;
419  i=2;output;
420  run;
NOTE: The data set WORK.A has 2 observations and 1 variables.

421  data b;
422  x=3;
423  run;

NOTE: The data set WORK.B has 1 observations and 1 variables.

425  DATA C;
426    IF _N_ EQ 1 THEN MERGE A B;
427    ELSE SET A;
428  RUN;

NOTE: There were 2 observations read from the data set WORK.A.
NOTE: There were 1 observations read from the data set WORK.B.
NOTE: There were 2 observations read from the data set WORK.A.
NOTE: The data set WORK.C has 3 observations and 2 variables.

I think in this case you should use POINT= option or sth else ;-).
