With both COBOL Compilers on BS2000 (COBOL85 rsp COBOL2000) a
sort-control register is not supported; possible special options for
sorting are supported by language means (sliding window for 2 digit
century date rsp special code sets); both Compilers support
SORT-MODE-SIZE and SORT-FILE-SIZE for improving sorting efficiency.
