The Notes

Each fitting is made up of 8x8 tiles. The data string describes where these tiles should be placed.

When drawing a fitting a 'cursor' is used, the same way PRINT works in BASIC, which is updated to the next character cell when a tile is drawn. This cursor can be moved to any location on the screen.
