/* 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 SQL
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).
