SUBROUTINE ADI1_MKFILE( LOC, ACCESS, ID, STATUS )
*+
*  Name:
*     ADI1_MKFILE

*  Purpose:
*     Make a bona fide HDSfile object given a locator

*  Language:
*     Starlink Fortran

*  Invocation:
*     CALL ADI1_MKFILE( LOC, ACCESS, ID, STATUS )

*  Description:
*     {routine_description}

*  Arguments:
*     LOC = CHARACTER*(DAT__SZLOC) (given)
*        Locator to HDS file object
*     ACCESS = CHARACTER*(*) (given)
*        The access required with the locator
*     ID = INTEGER (returned)
*        The HDSfile object
*     STATUS = INTEGER (given and returned)
*        The global status.
