Previous: Changes in V4.2
The following describes the most significant changes which occurred in HDS
between versions V4.2 and V4.3 (the current version).
- 1.
- A change has been made to the way that data pointers are
allocated by HDS, so that the new CNF_PVAL
function (described in SUN/209) may be used when
passing pointers using the "%VAL" facility (see
§
). Use of this function remains optional on
currently-supported platforms, but it may be required if Fortran
software which holds pointers in INTEGER variables is required to run
in circumstances where memory pointers require a longer variable for
storage.
Use of CNF_PVAL is recommended in all new Fortran software which uses
HDS pointers.
- 2.
- The maximum number of objects which may be simultaneously mapped
via CMP_ routines has been increased to 1024.
- 3.
- This document (SUN/92) has been updated to
reflect the above changes.
