SUBROUTINE DYN_UNMAP( PTR, STATUS ) *+ * Name: * DYN_UNMAP * Purpose: * Unmap memory allocated by DYN * Language: * Starlink Fortran * Invocation: * CALL DYN_UNMAP( PTR, STATUS ) * Description: * Unmap memory allocated by DYN. It is an error to supply this routine * with an address not allocated by DYN. * Arguments: * PTR = INTEGER (given) * Address of a memory section allocated by DYN * 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: * DYN Subroutine Guide : http://www.sr.bham.ac.uk/asterix-docs/Programmer/Guides/dyn.html * Keywords: * package:dyn, usage:public * Copyright: * Copyright (C) University of Birmingham, 1995 * Authors: * DJA: David J.
