To use the program, just execute it from the “Run” dialog window (use the “Browse” feature if necessary). Enter the required parameters as prompted. Use your own sign convention for east or west longitudes and north or south latitudes. But, obviously, if the map crosses the Equator, either north or south latitudes will have to be negative, and if the map crosses the Prime Meridian, either east or west longitudes will have to be negative. It’s your choice, but then it’s up to you to correctly interpret the results. If it crosses the 180th meridian you’ll have a problem that will require some data manipulation later on. Finally, note that the program will not work if the map includes either pole. The higher values may be on left or right, top or bottom. The program will decrement or increment values as necessary. When the ‘THE RESULTS WERE WRITTEN TO “C:\LATLONG.TXT”’ message is written, the program is finished, and the DOS window can be closed. The file can then be found in your main directory.
