invalid key specification

  Explanation:  The key field size, position, data type, or order
  is incorrect within the key definition.  Positions start at 1
  and cannot be greater than the maximum record size.  Record size
  must be less than or equal to 32,767 for character data; 1, 2,
  4, 8, or 16 for binary data; and less than or equal to 31 for
  decimal.

  User Action:  Check the command string key specifiers.
