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