Field 3 : Name - the waypoint name, use the correct length name to suit the GPS type.
Field 4 : Description.
Field 5 : Route Color as displayed on map (RGB).
Route Waypoint Record

Field 1 : W - indicating route waypoint details.
Field 2 : Route Number - location in array of routes
Field 3 : Number - this is the location in the array of route waypoints, this field is now ignored.
Field 4 : Wp Number - this is the number of the waypoint (the Wp number within the GPS for lowrances)

While all the waypoint details are stored with each route it is always the waypoints loaded on the map which have priority, in other words if a waypoint on the map has the same name and/or array number location as a waypoint in a route loaded from a route file the waypoint on the map could replace the waypoint currently loaded from the route record. This occurs when the user presses the relink waypoints button on the Route Editor.

Date Format

Delphi stores date and time values in the TDateTime type. The integral part of a TDateTime value is the number of days that have passed since 12/30/1899. The fractional part of a TDateTime value is the time of day.

Following are some examples of TDateTime values and their corresponding dates and times:

0 - 12/30/1899 12:00 am
2.75 - 1/1/1900 6:00 pm
-1.25 - 12/29/1899 6:00 am
35065 - 1/1/1996 12:00 am
