===================================================================================

- "Version()" shows the release version of Yacas, the starting of Yacas shows
the Yacas release and the client&server versions and the "Example()" comment;

is 5KB, and Yacas will be closed if the output is greater than 5 KB or

Changes in Yacas for EPOC32 v1.0.53rev2 and Client&Server 1.20 (November 18th 2003)
===================================================================================

- the scroll bars are turned on by default and the vertical and
horizontal history size of them are increased, from 10x10 to 500x25
(lines x characters), taking just more 40 KBytes of RAM;

- "Shift+Del" keypress works deleting text on the right (as a delete),
and "Del" keypress deletes text on the left;

- "Fn+Left" keypress works as "Home" (the cursor goes to the beginning of the
input line) and "Fn+Right" as "End" (the cursor goes to the end);

- "Ctrl+Left" keypress jumps 10 characters to the left and "Ctrl+Right"
keypress jumps 10 characters to the right;

- "Up" and "Down" keypresses also show the current line and the total lines
of the history in a message window;

- "Shift+Left", "Shift+Right", "Shift+Ctrl+Left" and "Shift+Ctrl+Right"
allow to select a region on the current input line (during the
selection, the lines above the cursor are also show inverted but it does
not affect the selection of the region);

- "Copy" & "Paste" now work but just inside Yacas, i.e., they do not
export & import to the EPOC32 clipboard (available to other application);

- the history file is not clipped to the current history position when
exiting Yacas on EPOC32.


Changes in Yacas for EPOC32 v1.0.53rev2 and Client&Server 1.30 (December 2nd 2003)
==================================================================================

- trailing backslash "\" at end of each continued line makes possible
  the use of commands spanning multiple input lines; 

- messages "Starting Yacas..." and "Running..." are shown when starting
  Yacas and when a calculation is running;

- line numbers are shown in input and output heads, i.e., "In(n)>" and "Out(n)>"

- the calculation time in seconds is displayed between "In(n)>" and "Out(n)>";

- "Esc" aborts the history navigation;

- removed extra empty line after error message, between print output and "Out(n)>"
  and in the end of outputs using "PrettyPrinter("PrettyForm")";

- the command "FindFile" now works;

- the command "ToFile" is now able to create output text files if they do not
  exist;

- fixed error on "Inverse(A)" and "SolveMatrix(A,vec)" when the matrix A
  has null determinant, so the Yacas server on EPOC32 is not closed;

- "FormulaMaxWidth" is set to 80 characters so "PrettyForm" can better
  use the screen of EPOC32 machines;

- uncompressed scripts can be loaded, using up to 0.5 MByte less of RAM than when
  loading the compressed "scripts.dat".
