delete them. Marking or unmarking a waypoint for deletion only requires left mouse clicking on the number of the

waypoint in the left-hand column. Since the program does not scan the entire file for comparison to any given waypoint,

it is necessary for you to make sure the file is pre-sorted by either Lat, Lon or Loran TDs. If the program finds any

exact duplicates during its search, it will delete them automatically. You will see blanked waypoints if this happens.

Exact duplicates are alike in every way. To continue searching, use the Edit>FIND NEXT routine or right mouse click

on the spreadsheet. The left/right mouse click technique makes it much faster to delete waypoints and advance to the

next find.

You will see in the header, the words: “[Duplicate search ON]”when duplicate search is active. It is active until finished

or canceled. Normally, no marked waypoints are actually deleted until the routine has gone through the whole file and

reports no more duplicates found. However, if you have a large file and have to leave the job before it is finished, you

get the chance to save the changes as you exit. Just select Find Duplicates again to uncheck the selection. A dialog will

appear giving you 3 choices. They are: Exit and delete the waypoints already marked, Exit without deleting anything, or

Cancel (don’t Exit).

To change the duplicates search criterion, go to TOOLS >USER PREFERENCES >Set Duplicates. Here you can

set the thresholds for near duplicates and the criterion for exact matches.

2.10 Find Duplicated Names

Most GPSs will not tolerate duplicated names. They will only keep one of each name, so some waypoints can get lost if

you are exporting a file to the GPS. This routine will identify which, if any, names are duplicated and let you change

them. Names that are linked to the record numbers are inherently not duplicated. If, however, you enter fixed numbers

for some names, then there exists the possibility that there will be duplicates that are not noted as such. To avoid this,

use numbers that cannot be the same as linked waypoints. One example is that linked names will be passed to the GPS

with 4 or 5 digits like 0001. Therefore, if you want to name a waypoint with 3 digits like 001, that is OK. To make the

job easier, sort the file by Name first. That will place all the duplicated names together (except those linked to record

numbers). The routine runs from the first name to the last, (ignoring linked names) every time it runs. It has to do this

since your fixing of a duplication by changing the name may create a new duplication.

3. DISPLAY MENU

The selections in this menu control the way the data is displayed on the screen. It could be called View. There are three

predefined spreadsheet formats; one user specified spreadsheet format, one basic graphical format and one NOAA chart

format. If Loran features are hidden, related formats will be too.
