Reduce complexity by exploiting DFSORT / ICETOOL
DFSORT has evolved far beyond simple sorting. This chapter demonstrates why you might consider DFSORT functions to replace batch steps that you have written yourself to perform tasks that can be done by standard functions and features provided by the z/OS environment. You might want to consider DFSORT for the following reasons:
•DFSORT statements are less complex to code and maintain than self-written code.
•DFSORT functions have the potential to be more computationally efficient than self-written ...
