IRI CoSort has been successfully converting JCL sort operations to Unix, Linux, and Windows systems for more than 20 years. Free metadata conversion utilities (mvs2scl and vse2scl) in the CoSort package translate z/OS (MVS) and VSE JCL parms written for IBM DF-SORT, CA-SORT, or SYNCSORT, into CoSort's SortCL job scripts.
SortCL can accomplish all the functions of mainframe sort software on "open systems" ... usually faster, and certainly cheaper. And beyond the migration, there are many application modernization benefits and more data management capabilities.
