SUBROUTINE ADI2_ADDKEY( HDUID, KEY, VALUE, CMNT, STATUS ) *+ * Name: * ADI2_ADDKEY * Purpose: * Read keywords from an HDU and store * Language: * Starlink Fortran * Invocation: * CALL ADI2_ADDKEY( HDUID, KEY, VALUE, CMNT, STATUS ) * Description: * {routine_description} * Arguments: * HDUID = INTEGER (given) * HDU to add key to * KEY = CHARACTER*(*) (given) * Name of keyword. Prefix with '@' to inhibit HDU modification flag * being set true. Prefix with ',' to only write the comment * VALUE = INTEGER (given) * ADI identifier of value * CMNT = CHARACTER*(*) (given) * Comment. Use '~' for standard comment * 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:private * Copyright: * Copyright (C) University of Birmingham, 1995 * Authors: * DJA: David J.
