SUBROUTINE ADI_FTRACE( ID, NLEV, PATH, FILE, STATUS ) *+ * Name: * ADI_FTRACE * Purpose: * Return text description of file position of identifier * Language: * Starlink Fortran * Invocation: * CALL ADI_FTRACE( ID, NLEV, PATH, FILE, STATUS ) * Description: * Returns a description of the full specification of a file based * data object. This is split into 2 parts. The FILE part gives the * operating system filename containing the data object. The PATH * contains any sub-file specification required. NLEV contains a * count of the number of levels of sub-structure within the PATH * value. * Arguments: * ID = INTEGER (given) * ADI identifier of file object * NLEV = INTEGER (returned) * Number of hierarchy levels * PATH = CHARACTER*(*) (returned) * Sub-file path * FILE = CHARACTER*(*) (returned) * File specification * STATUS = INTEGER (given and returned) * The global status. * Examples: * {routine_example_text} * {routine_example_description} * Pitfalls: * {pitfall_description}... * Notes: * {routine_notes}... * Prior Requirements: * {routine_prior_requirements}... * Side Effects: * {routine_side_effects}... * Algorithm: * {algorithm_description}... * Accuracy: * {routine_accuracy} * Timing: * {routine_timing} * 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:public * Copyright: * Copyright (C) University of Birmingham, 1995 * Authors: * DJA: David J.
