Updated brandybasic to 1.0.16

Version 1.11  17/09/2001

Darren Salt (ds@youmustbejoking.demon.co.uk) contributed a number
of the changes in this version of the program.

-  Added support for reading Acorn five byte floating point
   values (Darren Salt).

-  Improved support for reading and writing Acorn eight byte
   floating point values on machines that use a different format
   for this sort of number to what Acorn use (Darren Salt).

-  Added support for reading gzip'ed files under Linux (Darren
   Salt).

-  The Linux version of the program can be installed using
   'configure' (Darren Salt).

-  Added code to detect the format of eight byte floating point
   numbers on the platform on which the interpreter is running.
   This is used when reading and writing such values (DD, based
   on original code by Darren Salt).

-  The first line of a program in text form is now ignored if
   it starts with a '#' in all versions of the interpreter.
   This only used to be supported in the NetBSD and Linux
   versions.

-  Changed handling of syntax errors detected when a line is
   tokenised. The interpreter now puts out a slightly more
   meaningful 'syntax error' message if a program with such
   an error in it is run instead of 'STOP'.

-  DIM statements of the form 'DIM abc%!8 100' are now
   dealt with correctly. Previously the code always wanted
   a variable as the location at which to store the address
   of the byte array and did not allow the use of an
   indirected expression. This was an oversight in the code
   and has now been fixed.

-  Fixed bug where the string memory management was not being
   reset under certain conditions when a program was edited.
   The program was being corrupted if a string expression was
   evaluated immediately prior to editing the program and then
   again immediately afterwards.

-  Fixed bug in ERROR statement code where ERROR 0,<text>
   was not being treated as a fatal error, that is, the
   error could be trapped by ON ERROR. Also fixed problem
   where ERR was not returning the user-supplied error
   number after an ERROR statement.

-  Fixed bug in handling of ON ERROR LOCAL where a storage
   overwrite was causing the interpreter to abort with a
   'interpreter has gone wrong' message when restoring LOCAL
   variables to their original values when dealing with an
   ENDPROC after branching to the statements after the ON
   ERROR LOCAL.

-  Fixed bug in READ statement that affected the reading of
   strings in cases such as 'READ a$,b$: DATA abcd,', that is,
   there is nothing after the last comma in the DATA statement.
   It should return a null string, but the code was skipping to
   the next DATA statement instead.

Version 1.12  01/12/2001

-  Split interpreter.c into four files and moved some stuff
   around. Renamed some files.

Version 1.13 28/11/2002

-  Included new RND code written by Crispian Daniels.

-  Included fixes for various graphics problem written
   by Crispian Daniels.

-  Incorporated new MacOS target written by Crispian
   Daniels.

-  Incorporated new FreeBSD target written by Dirk Engling.

-  Removed limit on the number of command line arguments
   returned by ARGV$.

-  Fixed problem in Unix version of program where screen
   output was not being displayed before using OSCLI.

-  Added new VDU function. This returns the value of the
   specified RISC OS VDU variable.

-  Added new function COLOUR. This returns a value that
   represents the closest colour to the colour with the
   specified colour components in the current screen
   mode.

-  Added missing GCOL <red>,<green>,<blue> statement

-  Added extended form of GCOL statement: GCOL OF ... ON

-  Added extended form of COLOUR statement: COLOUR OF ... ON

-  Added extended MODE statement: MODE <x>,<y>,<bpp>,<rate>

-  Extended the DIM statement to support the
     DIM <variable> LOCAL <size>
   version of the statement.

-  Checked program compiled and worked using the Castle C
   compiler.

Version 1.14  28/07/2003
-  Quick hack to fix DIM ... LOCAL problem. The problem was
   that the code to check that writes using indirection
   operators were to legal addresses blew away writes to
   byte arrays on the stack. I have removed this check so
   that the stack can written to.

Version 1.15 16/08/2003
-  Added '*key' to allow strings to be defined for
   function keys as on a BB Micro or RISC OS machine.

Version 1.16 25/01/2004
-  Added OpenBSD target (changes supplied by Julian Smith).

-  Added Amiga target (changes supplied by Stefan Haubenthal).

-  Fixed bug in tokenisation code where any keyword immediately
   followed by a '.' was taken as abbreviated and the '.'
   always skipped. This should not have been happening when
   the full keyword was supplied. The '.' in this case is the
   start of a floating point number.

-  Changed the handling of the function 'TOP'. Brandy used to
   have a token for this function but it is not how the RISC OS
   Basic interpreter treats it. It uses the token for 'TO'
   followed by the letter 'P'. This means that the interpreter
   determines from the context whether this is the function 'TOP'
   or the keyword 'TO' followed by a variable name starting
   with 'P'. Brandy now works the way the RISC OS interpreter
   does.

-  Fixed bug in handling of 'ERR'. The number of the last error
   was not being saved so that it could be referenced using
   ERR except in the case of errors raised via 'ERROR'. This
   bug was introduced in 1.11 when the *opposite* problem was
   fixed!

-  Added '*' command emulation to versions running Unix-type
   operating system. Previously it was DOS only.

-  Changed handling of OS commands to that leading blanks and
   '*' are removed first.

-  Added new command line option '-nostar' to stop program
   checking all '*' commands to see if they are emulated by
   the interpreter.

-  Tidied up the output on 'help' which shows the where the
   Basic program and variables are.
