SUBROUTINE HSI1_NEW( NARG, ARGS, OARG, STATUS ) *+ * Name: * HSI1_NEW * Purpose: * Create new history in an HDS file * Language: * Starlink Fortran * Invocation: * CALL HSI1_NEW( NARG, ARGS, OARG, STATUS ) * Description: * Creates the HISTORY structure in an HDS file to another. Existing * structure is deleted if present. * Arguments: * NARG = INTEGER (given) * Number of method arguments * ARGS(*) = INTEGER (given) * ADI identifier of method arguments * OARG = INTEGER (returned) * Output 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: * Creates a PSF_SLOT property on the property list of the first * argument if one is not already present. * Algorithm: * {algorithm_description}... * Accuracy: * {routine_accuracy} * Timing: * {routine_timing} * External Routines Used: * DAT: * CMP_PUT0x - Write value of HDS component * DAT_ANNUL - Release an HDS locator * DAT_ERASE - Erase an an HDS component * DAT_FIND - Find an HDS component * DAT_NEW[0x] - Create new HDS component * DAT_THERE - Does an HDS component exist? * Implementation Deficiencies: * The constants in this routine should be loadable resources. This * would enable the user to turn off all history creation (somehow). * References: * HSI Subroutine Guide : http://www.sr.bham.ac.uk/asterix-docs/Programmer/Guides/hsi.html * Keywords: * package:hsi, usage:private * Copyright: * Copyright (C) University of Birmingham, 1995 * Authors: * DJA: David J.
