*+
*  Name:
*     ADI2_KCF2A

*  Purpose:
*     Copy a FITS keyword value to an ADI object component

*  Language:
*     Starlink Fortran

*  Invocation:
*     CALL ADI2_KCF2A( HDUID, KEY, OBJ, MEMBER, OK, STATUS )

*  Description:
*     {routine_description}

*  Arguments:
*     HDUID = INTEGER (given)
*        ADI identifier of FITShdu object
*     KEY = CHARACTER*(*) (given)
*        Name of keyword whose value is to be copied
*     OBJ = INTEGER (given)
*        ADI identifier of structure or class instance whose component is
*        to be written
*     MEMBER = CHARACTER*(*) (given)
*        Name of member to write if keyword data is defined
*     OK = LOGICAL (returned)
*        True if keyword data copied successfully
*     STATUS = INTEGER (given and returned)
*        The global status.

*  Check inherited global status.

*  Look for keyword
      CALL ADI2_CFIND_KEY( HDUID, KEY, .FALSE., KID, .FALSE., STATUS )

*  Does our keyword exist?
      IF ( KVID .NE. ADI__NULLID ) THEN

*    Locate the value
        CALL ADI_FIND( KID, 'Value', KVID, STATUS )

*    Make a copy
        CALL ADI_COPY( KVID, MVID, STATUS )

*    Release keyword value
        CALL ADI_ERASE( KID, STATUS )

*    Write object component
        IF ( MEMBER .GT. ' ' ) THEN
          CALL ADI_CPUTID( OBJ, MEMBER, MVID, STATUS )
        ELSE
          OBJ = MVID

*    Set return flag

        ELSE
          CALL ERR_ANNUL( STATUS )

*    Release keyword cache object

      END IF

*  Report any errors
      IF ( STATUS .NE. SAI__OK ) CALL AST_REXIT( 'ADI2_KCF2A', STATUS )
