KALKULATOR - VERSION HISTORY
============================
VERSION 1.50 - 97/03/15
Double-clicking on the Result Variable is now equivalent to
pressing the Enter Key (evaluates the rexpression and stores
the result in the displayed variable).
Bug fix: "t" is no longer inserted at the beginning when not
appropriate (mouse entry only).
VERSION 1.49 - 97/03/10
User-defined functions can now be loaded from, or saved to a
disk file, to allow for creation of function libraries.
Clicking on the line number allows to jump to an expression
line selected from a pop-up menu.
An option to insert the last result as "t" at the beginning
of an expression starting from +, û, * or / has been added;
the Panel Options has been appropriately modified.
Color is used in input dialogs to show the active entry field.
Sound effect at startup has been removed.
VERSION 1.48 - 97/01/31
Changes in physical constants: new values added, some of the
old ones corrected or revised.
VERSION 1.47 - 97/01/02
The two missing pixels at the bottom of the Display Line
have been restored (16-bit version only).
Font files reverted from .FNT to .FON standard to avoid
problems in the 16-bit version.
VERSION 1.45 - 96/12/26
A Result Variable can be now assigned to every expression;
this makes chained calculations easier.
The Expression Line now stays highlighted after an expression
has been evaluated; its contents will be erased after any new
input.
Introduced a simpler method to add a regression line to an
existing graph canvas.
The graph Undo button now works as a toggle.
The tabbed control widgets in the Main Panel have been
reworked (somewhat different look and feel).
The program will now find the fonts even if the working
directory is not set to the program directory.
VERSION 1.42 - 96/11/20
A new feature: simultaneous function graphs of any combination
of expression lines, with joint min/max evaluation.
The Main Panel buttons (and some others) have been replaced
with a different button type, using significantly less of
Windows' resources (especially important for Win 3.1 users).
General cleanup of the help file.
New update and upgrade policy: all free for the lifetime of
the program, without version limit.
VERSION 1.40 - 96/11/05
A major new feature: computer math operations, including
conversions between binary, octal, hex and decimal, also
8, 16 and 32-bit word lengths.
The Linear Algebra and Polynomial Root panels are now called
from the new Extras menu (their buttons are no longer in the
Bottom Line).
For users whose email programs have problems handling file
attachements: Kalkulator will now create a registration key
file when you enter your key code obtained in email (in mail,
by phone, etc.)
The missing exponent in the Boltzmann constant has been added.
VERSION 1.31 - 96/08/29
A bug fix: no more locking when a data buffer is sorted while
scrolled down (16-bit version only).
The default directory for statistical and linear algebra files
is now always set to the Kalkulator home directory, which could
not be the case if the program was executed from a third-party
shell (registered copies only).
New topics in the HOWTO.TXT file.
VERSION 1.30 - 96/07/15
Problem with saving multiple .kal files has been fixed.
VERSION 1.29 - 96/06/23
There is now an option to keep Kalkulator window on top in the
Mini Layout mode.
The Escape key no longer closes the graph panel; use Enter.
A check has been added against too narrow plot limits.
A bug occuring in data point insert operation in the XY mode
has been fixed.
VERSION 1.28 - 96/06/12
The definition of harmonic average has been corrected.
Small touch-ups in the program and in its Help file.
VERSION 1.27 - 96/05/29
Fixed problem (?) with screen fonts on some systems.
Small changes in how Data Grids handle errors in user input.
New ordering information in the Help file: HOW TO REGISTER
BY PHONE, FAX OR ON THE WEB USING A CREDIT CARD.
VERSION 1.25 - 96/05/14
An autoscroll option has been added: the Expression line
will scroll to the next expression slot upon a successful
computation.
A [Clear] button has been added to the Root Panel.
VERSION 1.24 - 96/04/22
A new feature: finding real and complex roots of polynomial
equations with real coefficients (linear, square, cubic;
also quartic in the registered version).
Pressing the F1 key will now bring context-sensitive help in
most of the dialog boxes.
VERSION 1.23 - 96/03/31
A bug, introduced in V1.21 has been fixed: Kalkulator no
longer refuses to do sums and derivatives.
VERSION 1.21 - 96/03/18
32-bit: first release for Windows/95
16-bit: brought in sync with the 32-bit version
VERSION 1.20 - 96/03/12
A major new feature: linear algebra operations (matrix and
vector algebra, matrix inversion, systems of simultaneous
linear equations).
The editor for data buffer has been redesigned: now it uses
a data grid.
The maximum length of an expression has been increased to
72 operands/operators or 120 characters (registered copies).
The reciprocal function has been renamed from inv to rcp.
A bug fix: no more lockups when the user attempts to perform
column-wise data buffer computation if arithmetic errors
occur at some of the points.
VERSION 1.10 - 96/02/12
A maintenance release (despite round version number). Fixed bug
causing non-rounded display of some values describing plots in
log scale.
VERSION 1.09 - 96/01/14
Sound effects added.
Important ONLY for some European users: a "." is now used as
the decimal point, regardless of regional settings.
VERSION 1.07 - 95/12/14
Expressions, not just values, are accepted wherever numerical
input is expected. A "Mini Layout" option introduced. Physical
constants added.
VERSION 1.04 - 95/11/25
Workaround around a compiler bug, affecting user functions.
VERSION 1.00 - 95/11/11
The original release.
