KEYVALUE
Type: Adverb    (array(2))
Use:  To specify the value of a numeric-valued keyword
      parameter.  The value is KEYVALUE(1) + KEYVALUE(2) after
      both are separately converted to double precision.  This
      allows the user to specify a higher precision number.
      If KEYVALUE(2) = KEYVALUE(1), then the value is taken to
      be just KEYVALUE(1).
Null value:   none.
Verbs:
  PUTHEAD....Puts a new value in the header field described by
             the FITS keyword in adverb KEYWORD.  There is no
             default for KEYVALUE.
  GETHEAD....Gets a parameter value from the header field
             described by the FITS keyword in adverb KEYWORD.
