SUBROUTINE AFLINK( STATUS ) *+ * Name: * AFLINK * Purpose: * Writes a file reference to a source dataset * Language: * Starlink Fortran * Type of Module: * ASTERIX task * Invocation: * CALL AFLINK( STATUS ) * Arguments: * STATUS = INTEGER (Given and Returned) * The global status. * Description: * Writes the logical file link specified by the user to the specified * source dataset. This link can be used subsequently by ASTERIX to load * the linked file automatically. Supplying a null value for the * linked file results in the link being deleted. * Usage: * aflink {parameter_usage} * Environment Parameters: * INP = UNIV (update) * Source dataset * LINK = CHAR (read) * The logical name of the link * LFILE = UNIV (read) * The file to be linked, or null * 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} * Implementation Status: * {routine_implementation_status} * External Routines Used: * {name_of_facility_or_package}: * {routine_used}... * Implementation Deficiencies: * {routine_deficiencies}... * References: * {task_references}... * Keywords: * aflink, usage:public * Copyright: * Copyright (C) University of Birmingham, 1995 * Authors: * TJP: Trevor Ponman (University of Birmingham) * DJA: David J.
