	BRAIN AID PROLOG V 1.2 Demo



This file covers the following topics:

  1. Known Bugs
  2. Last Changes


 1. Known Bugs
 -------------

- The Windows I/O server WIO will open an existing file in the PATH or Windows
  directory instead of creating a new one in the current directory.

- The PROLOG compiler has difficulties parsing atoms that include backslashes
  ('\') in atoms that are not enclosed by parentheses ('or"). This does not
  concern predicate calls that are resolved at compile time (like '\='), but
  atoms passed as arguments.

  For example:

	A \= B			% works
	exec( A\=B )		% does not work
	exec( '\\='(A,B) )      % works
	exec( not( A=B ) )	% works (this is the recomended work-around)

  The error causes the assembler to hang. An error message is displayed in
  the console window (codegen internal error). You will have to reboot the
  system after this has occurred.

- Support: We are currently experiencing slight difficulties with our mail
  server. Don't get worried if we do not reply to your mail within a day, this
  might take a week.

- The 'found.net' file written by a generic boot overwrites an existing file
  without truncating it. This causes a problem if you have booted a larger
  network before and know need the 'found.net' file as input for the
  Network Compiler. In that case, delete the old 'found.net' and boot again.


 2. Last Changes
 ---------------

- To support the PD editor PFE, we have included a file SHOW_PFE.BAP, that can
  replace the existing error serveer SHOWERR.LKD (rename and compile).

- The environment variables BBIN, BINC, BUSR and BLIB that are mentioned in
  the help file are not required, WIO sets them automatically. In case you
  want to change their values, edit the [Wio] section in WIN.INI.

- WIO now supports hardware that cannot be reset via the standard B004 link
  interface.
  Activate the "External Reset" option in the Setup dialog. WIO will then
  prompt for an external reset with a message box. Start your own reset
  program (for instance from a DOS box) and click Ok when the network is
  completely reset.
  While the message box is displayed, WIO will stop all link activity.
