SUBROUTINE ADI1_CCA2HT( ID, MEMBER, LOC, CMP, STATUS )
*+
*  Name:
*     ADI1_CCA2HT

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

*  Language:
*     Starlink Fortran

*  Invocation:
*     CALL ADI1_CCA2HT( ID, MEMBER, LOC, CMP, STATUS )

*  Description:
*     Copies an ADI data member to an HDS object if the member data is
*     defined. Selects the type specific routine to use on the basis of
*     the ADI object's class.

*  Arguments:
*     ID = INTEGER (Given)
*        The ADI identifier containing the data member
*     MEMBER = CHARACTER*(*) (Given)
*        The name of the data member to copy
*     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
*     STATUS = INTEGER (Given and returned)
*        The global status.

*     {routine_example_text}
*        {routine_example_description}
