Introduction
------------------------------------------------------------------------------

The Comix RDD, hereafter referred to simply as Comix, provides the highest
performance indexes available.  Comix works with Clipper 5.2.

The key advantages of Comix include:

o   Complete compatibility with standard INDEX syntax and use.

o   Use of standard CDX and FPT file formats which enables easy use of a
    wide range of other third party products.

o   Multiple indexes per file (compound indexes).

o   Excellent index compression.

o   Excellent index creation times.

o   Excellent update performance.

o   Powerful but simple extensions to provide new capabilities with minimal
    additional syntax to learn.

o   Enhanced memo field capabilities including the ability to store binary
    data, improved space reuse, smaller block size, and control over block
    size.

o   Unlimited indexes per compound index and unlimited compound indexes per
    workarea.

o   Structural indexes (auto-use of compound index when the database is
    brought into use).

o   Ability to dynamically switch indexes from ascending to descending
    order.

o   Very high performance logical key number functions which allow easy
    creation of scroll bars and record n/total interfaces without degrading
    performance.

o   Index scoping to instantly restrict indexes to a specified range, and
    the ability to use CodeBlock's for scoping values to cleanly handle true
    one-to-many relationships.

o   Custom Built Indexes (complete control over adding and deleting keys
    from an index).
