SUBROUTINE ADI2_GETCIE( HDUID, CIID, ICARD, FORM, OBJID, STATUS )
*+
*  Name:
*     ADI2_GETCIE

*  Purpose:
*     Get a card index form and the object it points to

*  Language:
*     Starlink Fortran

*  Invocation:
*     CALL ADI2_GETCIE( HDUID, CIID, ICARD, FORM, OBJID, STATUS )

*  Description:
*     Write value of keyword to specified HDU. Any existing keyword value
*     is overwritten.

*  Arguments:
*     HDUID = INTEGER (given)
*        ADI identifier of HDU object
*     CIID = INTEGER (given)
*        The CardIndex structure for this HDU
*     ICARD = INTEGER (given)
*        The card number we're interested in
*     FORM = CHARACTER*(*) (returned)
*        The form of the object, [K]eyword, [C]omment or [H]istory
*     OBJID = INTEGER (returned)
*        ADI identifier of object holding card info
*     STATUS = INTEGER (given and returned)
*        The global status.
