The traditional APL ordering of the comparison functions used above, which was used at least as early as [[APL\360]], resembles a [[wikipedia:Gray code|Gray code]] ordering of the values which define the comparison functions. Adjacent values differ by only a change of one bit, but the list is not a true Gray code because it excludes the all-0 and all-1 combinations. | The traditional APL ordering of the comparison functions used above, which was used at least as early as [[APL\360]], resembles a [[wikipedia:Gray code|Gray code]] ordering of the values which define the comparison functions.
