  How does the SIx Driver differ from the DBFCDX Driver in Clipper 5.2?:

  While the SIx Driver's FoxPro flavor (SIXCDX) may seem very similar to
  the DBFCDX driver we licensed to CA for inclusion with Clipper 5.2x, there
  are some very major differences between the two.

  The DBFCDX Driver supplied with Clipper 5.2 basically provides what we
  call "The Three C's":

    Compound:  Store up to 50 index "tags" within one compound (CDX) index

    Compact Indexes:  The CDX and Compact IDX formats of FoxPro are
                      fully supported.

    Conditional Indexes:  INDEX ON <cExp> TO <cFile> FOR <cCondition>


  These are some of the current SIx Driver (SIXCDX) features which are NOT
  included in the Clipper 5.2 DBFCDX RDD:

    . VariFields (tm) - Dynamically-typed, variable length field storage
      in FPT/SMT memo fields

    . Integrated Fast Text Search technology (HiPer-SEEK)

    . Built-In Mach SIx Query Optimizer

    . Data Encryption - Protects your database and memo file data from
      viewing by unauthorized users

    . Data Compression - Compress FPT/SMT memo file data and/or external
      files

    . Database Event Triggers - Attach a "trigger" to various events

    . Subindexes

    . Roll-Your-Own (RYO) Indexes

    . Multi-Keyed, Free-Format Indexes

    . SCOPEd Indexes

    . Support for array storage in FPT/SMT memo fields

    . Memo Packing

    . Reuse of freed memo blocks

    . Adjustable FPT/SMT memo block size

    . Logical Index Position Functions

    . TURBOREAD

    . Wildcard SEEKs


  NOTE:  All of the features of the SIx Driver's SIXCDX flavor are also
         found in the SIXNSX flavor.
