*+
*  Name:
*     BDI_AXPUT1D

*  Purpose:
*     Put the named axis items as DOUBLE PRECISION vectors

*  Language:
*     Starlink Fortran

*  Invocation:
*     CALL BDI_AXPUT1D( ID, IAX, ITEMS, DIM, DATA, STATUS )

*  Description:
*     Writes the axis items specified by the ITEMS string as DOUBLE PRECISION
*     vector values.

*  Arguments:
*     ID = INTEGER (given)
*        ADI identifier of BinDS, Array or Scalar object, or derivatives
*        thereof
*     IAX = INTEGER (given)
*        Axis number of the items to be checked
*     ITEMS = CHARACTER*(*) (given)
*        List of axis items to be read
*     DIM = INTEGER (given)
*        Size of user buffer
*     DATA[] = DOUBLE PRECISION (given)
*        The data to write
*     STATUS = INTEGER (given and returned)
*        The global status.
