Syncsort™ MFX is a high performance sort/merge/copy utility. It is designed for the advanced facilities of the zSeries architecture and exploits the features of the z/OS operating system, but also supports the system architectures of IBM System/390 and compatible computers.
MFX is designed to conserve system resources, provide significant performance benefits, and operate efficiently in 31-bit or 64-bit environments.
MFX can be initiated through job control language or invoked from a program written in COBOL, PL/1, or Assembler language. A JCL-initiated sort is more efficient because MFX totally controls the sort execution, including I/O management and main storage management. Exit routines may be written in COBOL, C, FORTRAN, REXX, or Assembler language to give a JCL sort additional programming flexibility. Exits may also be in PL/1 when MFX is invoked by a PL/1 program.
