*+
*  Name:
*     ADI1_GETLOC

*  Purpose:
*     Extract locator from dataset object

*  Language:
*     Starlink Fortran

*  Invocation:
*     CALL ADI1_GETLOC( ID, LOC, STATUS )

*  Description:
*     Extract the locator from an object derived from HDSlocator.

*  Arguments:

*     LOC = CHARACTER*(DAT__SZLOC) (returned)
*        The HDS locator to the object
*     STATUS = INTEGER (given and returned)
*        The global status.
