waypoints and Loran to Lat/Lon conversions are not done on them. They are used, instead, to derive calibration

parameters (and, of course, as good waypoints).

If you enter an out of range number, an alert message shows you what the estimated number at the center of the area

would be and asks you to check your entry. Entries that are more than 200 miles or 1000 microseconds (both user

definable) from the "area center" are challenged.

The first two entry boxes have titles showing what Loran stations are expected. They are dimmed if Lat/Lon entry is

selected. The program has been designed to accommodate many different styles of Loran and Lat/Lon data. If the data

can be fit to any of the available Lat/Lon styles or Loran chains, it will be accepted. Common errors such as missing

decimal points in the Loran numbers or the wrong chain choice will, in most cases, be rectified automatically. In cases

where the number is ambiguous, the program will complain that it can't identify the waypoint. Use the Change Chain

button to select the appropriate chain pair if you are entering numbers not the same as shown on the box headers. It

brings up the following dialog. You can see, from the display below, what are representative Loran waypoints for each

of the chain choices. The chosen chain is shown in the window.

The second and third entry boxes are for Lat/Lon. If you enter numbers in LAT/LON, use one of three forms: degrees

and decimal degrees (DD.DDD) or degrees, minutes and decimal minutes (DDMM.MM) or degrees, minutes, seconds

and decimal seconds (DDD MM SS.S). Thus 126 degrees, 7 minutes and 30 seconds north is written as either: 126.125,

12607.50, 126 7.50, or 126 7 30.0. South Latitudes and East longitudes are entered as negative numbers. If you want

these numbers automatically converted to Loran using the chain shown, check the Convert to Loran checkbox that

appears when you have selected Lat/Lon entry. Otherwise, you can convert them later from the menu TOOLS

>CONVERT TO LORAN.

The Rating is a 4-character field intended to hold information on how good or bad the spot is for fishing or diving, but

you can use it for anything you want. The Name field is the GPS short name of 6 to 16 characters. The Description

field is 32 characters and is intended for the waypoint description. The Comments field is 90 characters for any other

comments you may have. It may be used to indicate what dates you visited this spot or how much you caught. These

fields sort alphabetically by the rules described under SORT FILE. The name will be linked to the waypoint number for

any waypoints that you do not enter a name for.

Color, Icon, and Symbol are used for the graphics display and import/export modes and are set with drop-down lists.
