A Ray is part of a line from a starting square in one particular direction. Lines are either the orthogonal ranks and files or the diagonal lines, diagonals and anti-diagonals. The length of a ray varies from zero until seven squares. =Ray Directions= Following Compass rose gives the directions and single step increments of an 8x8 Board: northwest   north   northeast noWe        nort         noEa +7   +8    +9              \  |  /  west    -1 <-  0 -> +1    east / |  \          -9    -8    -7  soWe         sout         soEa southwest   south   southeast =See also=
