observation from the datasets

It doesn't look like you want to output ANY observations.
data want ;
set have ;
if _n_=1 and text='yyy' then stop;
run;
sorry i do .. my mistake ..
i want the following dataset with only 1st obs if text="yyy"
text id1 id2 id3
yyy 123 145 345
A simple variation on Tom's program handles both cases:
data want;
set have;
output;
if _n_=1 and text='yyy' then stop;
run;
