 /LOC handles location conversions. It will convert -
    NGR to latitude and longitude and also to an IARU locator.
    Latitude and longitude to an IARU locator.
    An IARU locator to latitude and longitude.
 It also works out the distance and bearing between locations.

 /LOC automatically works out what input format you have used.
 Permissible input formats are:-
    1. IARU locator, 4 or 6 characters can be input,
       e.g. IO92, or IO92XX. If you only input 4 characters,
       "LL" (the approximate centre of the square) is assumed for
       the 5th and 6th characters.
    2. NGR, you can input either 6 or 8 characters,
       with or without spaces e.g. - 
       TF3143, or TF 31 43, or TF312433, or TF 312 433
       If you only input 6 characters, the calculations
       are done for the approximate centre of the square.
    3. Latitude and longitude in d.m.sA d.m.sB format
       (d = degree, m = minute, s = second, A = N or S, B = E, or W)
       e.g. 52.58.14N 0.02.46W, or 52.58N 0.02W, or 52N 0W

 You first input your home location, which is converted as detailed
 above, then you can input as many other locations as you want.
 /LOC converts each of these locations and tells you the distance
 and bearing from your home location.

 Alternatively you can input a location on the /LOC command line,
 e.g. /LOC IN52NG. If you do this, /LOC uses the WinPack operator's
 QRA locator (as set up in Personal/BBS Info) for the home location
 and does an immediate calculation for the location that was input.
 This method is only useful to the WinPack operator or to someone
 living near enough to have the same QRA locator.

 All the maths are derived from original routines by GM4ANB,
 (all the errors in converting them for use in LOC are mine!)
