VMS / OpenVMS SORT MERGE Migration for x86 Intel Linux and Windows


VX/SOR is a full implementation of VMS / OpenVMS SORT MERGE from the SOR$ API set, the VX/DCL shell and also from the Linux shell. VX/SOR uses multi-file MERGE SORT techniques with quick-sort enhancements. VX/SOR call compatible library which provides the calleable interface for SOR$: SOR$BEGIN_SORT, SOR$END_SORT, SOR$INIT_SORT, SOR$MERGE, SOR$PASS_FILES, SOR$RELEASE_REC, SOR$RETURN_REC, SOR$SORT_MERGE, SOR$SPEC_FILE, SOR$STAT.

Calling SORT from the VX/DCL command line
