What is the maximum number of Sortwk data sets?
Up to 255 SORTWK datasets can be specified for intermediate process. If block set technique is not used and more than 32 datasets coded, only first 32 will be used during the sorting. SORTWKdd data sets can be on disk or on tape, but not both. SORTWKdd datsets disk types can be mixed.

What is the name of input DD statement used for merge?
Instead of the SORTIN DD statement, you use SORTINnn DD statements to define the input data sets. The SORTINnn DD statements name the input data sets, and tell how many data sets will be merged. You need one SORTINnn DD statement for each data set being merged.
