There be many a land lubber that knows naught of the pirate ways and gives direction by degree!
They know not how to box the compass!



Task description

 Create a function that takes a heading in degrees and returns the correct 32-point compass heading.
 Use the function to print and display a table of Index, Compass point, and Degree; rather like the corresponding columns from, the first table of the wikipedia article, but use only the following 33 headings as input:
[0.0, 16.87, 16.88, 33.75, 50.62, 50.63, 67.5, 84.37, 84.38, 101.25, 118.12, 118.13, 135.0, 151.87, 151.88, 168.75, 185.62, 185.63, 202.5, 219.37, 219.38, 236.25, 253.12, 253.13, 270.0, 286.87, 286.88, 303.75, 320.62, 320.63, 337.5, 354.37, 354.38]. (They should give the same order of points but are spread throughout the ranges of acceptance).


Notes;
 The headings and indices can be calculated from this pseudocode:
for i in 0..32 inclusive:
    heading = i * 11.25
    case i %3:
      if 1: heading += 5.62; break
      if 2: heading -= 5.62; break
    end
    index = ( i mod 32) + 1
 The column of indices can be thought of as an enumeration of the thirty two cardinal points (see talk page)..

dim direct$(22)
direct$(1)  = "y"      'by
direct$(4)  = "ast"    'East
direct$(13) = "orth"   'North
direct$(18) = "outh"   'Soutn
direct$(22) = "est"    'West

for i =1 to 32: read point$(i) :next i
 
html "<table border=1>" 
for i = 0 to 32
    hdng = i * 11.25
    if (i mod 3) = 1 then
        hdng = hdng +5.62
    else
        if (i mod 3) = 2 then hdng = hdng -5.62
    end if
    pointer = i mod 32 + 1
    html "<TR><TD align=right>";pointer;"</td><td>";compas$(hdng);"</td><td>";hdng;"</td></tr>"
next i
html "</table>"
end
 
function compas$(hd)
x = hd /11.25 + 1.5
if (x >=33.0) then x =x -32.0
  p$ = point$(int(x))
  for i = 1 to len(p$)
    compas$ = compas$ + mid$(p$,i,1) + direct$(max(asc(upper$(mid$(p$,i,1)))-65,0))
  next i
end function
