SUBROUTINE ADI2_FCLOSE( FID, STATUS )
*+
*  Name:
*     ADI2_FCLOSE

*  Purpose:
*     Close a FITSfile object

*  Language:
*     Starlink Fortran 77

*  Invocation:
*     CALL ADI2_FCLOSE( FID, STATUS )

*  Description:
*     Free FITSIO and system resources associated with the FITSfile object
*     supplied. It is assumed that all data has been written to the file
*     that will be required.

*  Arguments:
*     FID = INTEGER (given)
*        ADI identifier of the FITSfile object
*     STATUS = INTEGER (given and returned)
*        The global status.
