SICStus Prolog v.3 #6, for MSDOS
-------------------------------

1. Release notes
================

General, platform independent, release notes for v.3 #6 can be found
in the online manual or errata pages for the printed manual.

MSDOS specific notes:

* This version runs on MSDOS, DOS-prompts of Windows 3.X, Win95, NT
  and OS/2.
* The development system does not need the -b option to find the
  compiled Prolog boot file as described in the manual, although it
  can be used.
* File paths with both '/' and '\' as separator are accepted. SICStus
  returns paths using '/'. Note that '\', since it is escape
  character, must be stated as '\\' unless the prolog flag
  'character_escapes' is set to 'off'.
* All file names and paths are converted to lowercase when expanded by
  absolute_file_name/2 etc.
* File paths of the form '~/' are expanded using the values of the
  environment variable HOME. The form '~username/'
  is not expanded. The form '$VAR/' is expanded using the value of the
  environment variable VAR. (The form '%VAR%/' is not recognized.)
* Command line editing is provided (see CMDPROC.TXT).
* Saved states (save/1-2, save_program/1, restore/1) are not supported.
* Dynamic loading of foreign resources is not supported. The development
  system is statically linked with the C-coded parts of the following
  libraries: system, charsio, random, fastrw, db, clpfd.
* No Tcl/Tk interface.
* stream_select/3 is not supported.
* stream_interrupt/3 is not supported.
* library(timeout) is not supported.
* library(sockets): not supported.
* library(system): The following predicates are not supported:
  exec/3, popen/3.  kill/2 works only on the sicstus process itself.
