SUBROUTINE HSI_GETCTR( FID, HCID, STATUS ) *+ * Name: * HSI_GETCTR * Purpose: * Retrieves history control information from dataset * Language: * Starlink Fortran * Invocation: * CALL HSI_GETCTR( FID, HCID, STATUS ) * Description: * Retrieves history control information from a dataset. This contains * the original file creation date, the creator's name and the number * of history records in the dataset. * Arguments: * FID = INTEGER (given) * ADI identifier of the dataset * HCID = INTEGER (returned) * ADI identifier of the history control data * 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: * HSI Subroutine Guide : http://www.sr.bham.ac.uk/asterix-docs/Programmer/Guides/hsi.html * Keywords: * package:hsi, usage:public * Copyright: * Copyright (C) University of Birmingham, 1995 * Authors: * DJA: David J.
