  ERROR CODE:  F

  MESSAGE TEXT:  invalid key match specifier for key direction

  EXPLANATION:  A keyed READ used an invalid key match specifier for
  the direction of that key.  Use KEYGE and KEYGT only on ascending
  keys.  Use KEYLE and KEYLT only on descending keys.  Use KEYNXT and
  KEYNXTNE to avoid enforcement of key direction and match specifier.
