SUBROUTINE FRI_GET( FID, RNAME, RFILE, STATUS ) *+ * Name: * FRI_GET * Purpose: * Read a file reference by character string * Language: * Starlink Fortran * Invocation: * CALL FRI_GET( FID, RNAME, RFILE, STATUS ) * Description: * Write a file reference by character string. No checking is * performed to see if the named object exists, as this routine * may be used to write two mutually self-referencing files * which are not yet committed to disk (depending on the behaviour * of the underlying file interface). * Arguments: * FID = INTEGER (given) * ADI identifier of file to write reference to * RNAME = CHARACTER*(*) (given) * Logical name of reference to write * RFILE = CHARACTER*(*) (returned) * Name of object the link points to * 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: * FRI Subroutine Guide : http://www.sr.bham.ac.uk/asterix-docs/Programmer/Guides/fri.html * Keywords: * package:fri, usage:public * Copyright: * Copyright (C) University of Birmingham, 1995 * Authors: * DJA: David J.
