BINARY RELOCATABLE FORMAT. Binary relocatable format specifies absolute X and Y
coordinates in the range -16384 to + 16383 using 6 bytes. The value specified in the relocatable
origin command is taken to be the 0,0 point. The actual screen address is computed by the
terminal by adding the relocatable origin to the X,Y pair.
