Answer Posted / sulthan
OPNQRYF dynamically creates the records required according
to the parameterrs and this process could be slow. While
using logic files , we already have the a record fectching
path and it is faster. so if a program needs to be run
multiple times, use LF's and if once in a while, go for opnqryf.
