OF-83-07D From the Abstract: The program displays the quarter-quarter-quarter breakdown of a point in a section defined in feet from either the north or south line and east or west line. Use of the program speeds quarter-quarter-quarter determinations and reduces errors. Points located on a quarterline are denoted with an asterisk. An ideal section shape is assumed.
