DFSORT seems to be most useful where you need to sort more data than can be processed in storage - but I'm wondering how often that really needs to be done. I'm not so interested in utilities and databases calling it under the covers - more in applications that require records in a particular order. Nor am I saying that's wrong - I'm really just asking whether languages like Java provide opportunities to eliminate some sorting.
DFSORT, Syncsort, etc. use the CPC/UPT hardware instructions to implement the fastest sort on the platform.
Are there java methods that also do this? Or do they use relatively inefficient software-based algorithms?
