Example:

   To better understand the meaning of 1:N relations, let's take a look at
   the following example:

   A 1:N relation is created when it is necessary to relate more than one
   record of a child file to one record of a parent file. In the example
   shown, the information relative to an invoice is divided into two files:
   the header and the relative detail rows. A typical data entry example on
   these two related (1:N) files can be the following:

   The records of the detail rows contain a field called InvCod that
   identifies the invoice to which they refer.

   Other details on the previous relation:

   Relation                One to Many

   Parent                  InvHea (Invoice Header)

   Child                   InvRow (Invoice Details)

   Index                   InvRow1 (Expression: InvRow)

   Inherited fields        InvRow->InvCod := InvHea->InvCod

   This information is necessary for a List Box object so that it can move
   the record pointer during the different phases of the operation (not only
   to display, but also for example, to scan all the records of the related
   records to obtain an on-line total).

   The display cycle that, in the generated code, allows to manage how
   information, coming from two files is displayed, is organized the
   following manner:
