109 /* [HGM] Some notes about board sizes:
\r
110 In games that allow piece drops, the holdings are considered part of the
\r
111 board, in the leftmost and rightmost two files. This way they are
\r
112 automatically part of the game-history states, and enjoy all display
\r
113 functions (including drag-drop and click-click moves to the regular part
\r
114 of the board). The drawback of this is that the internal numbering of
\r
115 files starts at 2 for the a-file if holdings are displayed. To ensure
\r
116 consistency, this shifted numbering system is used _everywhere_ in the
\r
117 code, and conversion to the 'normal' system only takes place when the
\r
118 file number is converted to or from ASCII (by redefining the character
\r
119 constant 'a'). This works because Winboard only communicates with the
\r
120 outside world in ASCII. In a similar way, the different rank numbering
\r
121 systems (starting at rank 0 or 1) are implemented by redefining '1'.
