I know this is a very late response, but just for anyone looking in the future, MF-COBOL is not the same as ACUCOBOL, and they dont even both use VISION, only ACUCOBOL uses VISION. There is a tool available from IRI, for ACUCOBOL and VISION, or Rocket (The new owners of ACUCOBOL) has the XDBC available which can work well with migrating and/or integrating COBOL and a modern DB.
