II) Contents
  A) TDataMover- this is a component
    which can be used to move data
    from a source dataset, to a
    destination dataset.  This
    component maps expressions,
    which are evaluated per record
    in the source dataset, to a
    field names in the destination
    dataset to which this component
    appends the evaluated expressions
    into.  This component extends the
    TExpressionEval component so
    all functionality in that
    component is implemented in this
    component.

  B) TTextFileDataSet- this is a
    component which takes in a number
    of parameters which it uses to load
    a delimited or fixedfieldwidths
    text file as a READ-ONLY dataset.
    This component is derived from
    the TListDataset component,
    which is written by DrBob.

  C) TExpressionEval- An extensible string
    evaluator component.  Use evaluate
    to take in a string whose contents is
    in the following form:
    AString =   'strconstant' |
                #CharNum |
                fieldname | 
                functionname [ (AString [, AString ...] ) ]
                [+ AString]
    and yield the string result.  The
    functions which was referrenced as
    function name above, is a user
    defined delphi procedure or method,
    which is registered with the
    registerFunction.  These UDFs must be
    of type:

    function(ins: array of string): string;

    where ins are the input paramaters,
    and the resultant string is placed
    in place of the function in the
    expression.

  D) TListDataset- This is a base Dataset
    written by DrBob which can be extended
    to easily make your own datasets.

III. Notes
  	I have never tried this with Delphi3,
  so if you try it on Del3 and it works then
  tell me.  Or if you get it to work then
  mail me the modifications.  Thanx.

IV. Contact Me
  	Feedback is a good thing.  So mail
  me with comments, feedback, suggestions,
  and, of course, all modifications made to
  this software.
