For ex i have 4 records in a dataset.
Have dataset has these 4 records
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??????
