/*  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).
