This file is an exact copy of an APRSdos .HST track history file.
This makes it easy to build.  Using APRS, you just move the cursor
around on the map and use the INPUT-ADD command to mark the locations
you want to be in the file.  The only important parameters are the
location of the cursor and the name.  Just hit enter for all others.

The raw .HST file will look like this (the standard .HST format):
test1     +192158z3851.  N/07701.  W/object
test2     +192159z3859.5 N/07653.1 W/object
test3     +192159z3854.55N/07616.15W/object

Then bring this file into an editor and simply insert a three digit
LOCATION number in front of each line and a comma separator

001,test1     +192158z3851.  N/07701.  W/object
002,test2     +192159z3859.5 N/07653.1 W/object
004,test3     +192159z3854.55N/07616.15W/object

Then resave the file with the name of POINTS.TBL.  Notice that you
can put any kind of text into the file in any format (like these words
for example).  The only thing that APRSdos searches for is the first
3 bytes, looking for a 3 digit number match to the desired point.

AMBIGUITY:

Notice that "test2" and "test3" locations have 600 foot and 1 mile
ambiguity.  This then asures that multiple D7's that report their
position at that location will be randomized somewhat within the
ambiguity circle and will not all be on top of each other.  They 
are easy to resolve as you zoom in.
