C.PARAMETERS:     KEYNAME char*8   the name of the keyword (in)
C                 JFILE   integer  the XAS ordinal number of the file
C                                  to be scanned (in)
C                 FOUND   logical  .TRUE. if the keyword is legal (out)
C                 DEFINED logical  .TRUE. if the keyword was defined
C                                  or loaded from full header (out)
C                 TYPE    integer  numeric code for type of value
C                                  0 -> character
