If I run this code:
data new;
do i=1 to 3;
set mydata;
end;
run;
why there is only 1 obs in the data new? |

it won't write the observation to the new dataset unless sas
meets an output statement, or reaches the end of the data step
(the output statement will overwrite the default output at the end)
