/*  This is a generic table editing program. The table and fields to be
    edited are defined in the calling program.

    This program works in three passes.
    * Pass 1 (the last part of the program) displays the selected MySQL
      table in a scrolling table on the screen. Radio buttons are used to
      select a record for editing or deletion. If the user chooses Add,
      Change, Copy, View or Delete buttons.
    * Pass 2 starts, displaying the selected record. If the user chooses
      the Save button from this screen.
    * Pass 3 processes the update and the display returns to the
      original table view (Pass 1).
