Although I am not familiar with the internal design of DFSORT and other major sort products, it is certainly possible to design a sort which uses the page data sets by explicitely paging blocks of data out and back in without using demand paging. We designed our own sort which has just that capability and it runs considerably faster than running with SORTWK data sets.
This design does have drawbacks, such as the dedication of space for page data sets, which lasts for much longer than SORTWK data sets. However, with th price of DASD so low, it scarcely makes any difference any more.
