In case if I want to know whether a record exists in a file, which one do you prefer CHAIN or a SETLL and why ?

Question Posted / sandey243


In case if I want to know whether a record exists in a file, which one do you prefer CHAIN or a SETL..

Answer / sandey243

If you just want to know whether the record exists or not, SETLL is best as it just points to the record and doesn't store the data in to fields ( time saving ) where as CHAIN will read and stores the data in to fields ( time consuming ).
