SUBROUTINE ADI2_OPEN( FID, MID, ID, STATUS ) *+ * Name: * ADI2_OPEN * Purpose: * Attempt to open an FITS file. If the file is opened ok then the * FileHandle object pointed to by ID is updated. * Language: * Fortran * Invocation: * CALL ADI2_OPEN( FID, MID, ID, STATUS ) * Description: * Attempts to open the named file object as an FITS file. If successful * the routine stores the logical unit and HDU number on the property * list of the ID object. * Arguments: * FID = INTEGER (Given) * Name of the object on which FITS access to be attempted * MID = CHAR (Given) * File access mode * ID = INTEGER (Given) * ADI identifier of FileHandle object * STATUS = INTEGER (Given and returned) * The global status. * Examples: * {routine_example_text} * {routine_example_description} * Notes: * {routine_notes}... * Prior Requirements: * {routine_prior_requirements}... * Side Effects: * {routine_side_effects}... * Algorithm: * {algorithm_description}... * External Routines Used: * {name_of_facility_or_package}: * {routine_used}... * Implementation Deficiencies: * {routine_deficiencies}... * References: * ADI Subroutine Guide : http://www.sr.bham.ac.uk/asterix-docs/Programmer/Guides/adi.html * Keywords: * package:adi, usage:private * Copyright: * Copyright (C) University of Birmingham, 1995 * Authors: * DJA: David J.
