INDEX CONVERT

        [MRTCAL\]INDEX CONVERT [/FILE IndexFile]

    Check  if the index file version is the latest possible. If not, the as-
    sociated file on disk is automatically converted. The original  file  is
    backup'ed to another name.

    While  index  file version has very seldom evolutions, when this happens
    it is necessary to convert 'old' files opened in UPDATE mode beforehand,
    as MRTCAL writes only in latest version files.
