SUBROUTINE ADI1_CCH2AT( LOC, CMP, ID, MEMBER, STATUS )
*+
*  Name:
*     ADI1_CCH2AT

*  Purpose:
*     Conditional copy of HDS component to ADI data member 

*  Language:
*     Starlink Fortran

*  Invocation:
*     CALL ADI1_CCH2AT( LOC, CMP, ID, MEMBER, STATUS )

*  Description:
*     Copies an HDS object to an ADI data member if the HDS data is
*     defined. Uses the most appropriate ADI type for the HDS data.

*  Arguments:
*     LOC = CHARACTER*(DAT__SZLOC) (Given)
*        The locator to the HDS structure to contain the component
*     CMP = CHARACTER*(*) (Given)
*        The name of the new HDS component
*     ID = INTEGER (Given)
*        The ADI identifier containing the data member
*     MEMBER = CHARACTER*(*) (Given)
*        The name of the data member to copy
*     STATUS = INTEGER (Given and returned)
*        The global status.

*  Examples:
*     {routine_example_text}
*        {routine_example_description}
