hi,
For ex i have 4 records in a dataset.
data demog;
set have;
run;
Have dataset has these 4 records
name age
kevin 23
peter 28
louis 33
...
...
...
first the Input buffer is set blank or missing accordingly.
it reads the first observation writes to the dataset
It then goes to the beginning of the datastep. NOW how will SAS know that it has already read the first one AFTER RETURNING TO THE BEGINNING OF THE DATA STEP????
Could someone tell me the process how it works??????
Sorry about that,,,I went back to my Basics and learnt that it is because of the _n_=
Try running this little step to see how it works in more detail.
data new;
put 'BEFORE ' _n_= age= eof=;
set have end=eof ;
put 'AFTER ' _n_= age= eof=;
run;
