All,

I have the following dataset, if the value of the 1st observation in column text is "yyy" then output only first obs or else output all the
observation from the datasets

Case 1

have
text id1 id2 id3
yyy 123 145 345
zzz 899 134 878
ccc 881 jk kjk

want
text id1 id2 id3

Case 2

have
text id1 id2 id3
mmm 123 145 345
zzz 899 134 878
ccc 881 jk kjk

want
text id1 id2 id3
mmm 123 145 345
zzz 899 134 878
ccc 881 jk kjk

Thanks
Al

It doesn't look like you want to output ANY observations.

data want ;
  set have ;
  if _n_=1 and text='yyy' then stop;
run;

A simple variation on Tom's program handles both cases:

data want;

set have;

output;

if _n_=1 and text='yyy' then stop;

run;
