Warp + Calc = WarpCalc

Description
===========
The WarpCalc calculator package contains two scientific
calculators, one for the OS/2 command line (CLI) and one for
the OS/2 Presentation Manager (GUI). Both versions share the
same core capabilities. In addition to common calculator
features they allow the user to define his/her own symbols.
For documentation on the GUI version refer to the extensive
online help. Depending on the context, online help can be
called up by pressing F1 on the keyboard, selecting the help
items on the system menu or simply clicking the help button
in the current dialog.
For documentation on the CLI version have a look at 2nd last
section of this readme.
System requirements
===================
Both the CLI version and the GUI version are 32-bit OS/2
applications. Calc should run on OS/2 2.x and above.
WarpCalc runs on OS/2 3.x (Warp), but Warp 4 or later is
recommended for visual appearance. WarpCalc uses the
WarpSans font introduced with Warp 4. For Warp 3 users not
having this font it can be installed by replacing the
Warp 3 version of the file dspres.dll with an updated
version downloadable from the WarpCalc home page.
Installation
============
Neither the CLI version nor the GUI version requires any
special installation. Simply copy the included files to
a directory of your choice.
If you are using Warp 4, the WPS will create a program
object for WarpCalc when you drag the executable to your
desktop. If you want to start WarpCalc from the desktop
popup menu follow these steps:
1. Click mouse button 2 on the desktop.
2. Select "Properties" from the menu.
3. Click on the "Menu" tab.
4. Drag the WarpCalc program object over the
"actions on menu" list box and drop it.
Licensing
=========
WarpCalc is shareware. The great thing about shareware is
that you only have to buy what you use. The 30 day trial
period is absolutely free, but if you decide to use
WarpCalc even after this trial period have expired you must
register the software. The one-time cost of registration
grants you a lifetime license to use this version and all
upgrades on one computer at a time.
WarpCalc can be registered by contacting the author,
BMT Micro or one of their authorized distributors. Users
in The Netherlands, Belgium, France, Germany and
The United Kingdom, may register through BTSoftware in
their own currency via local bank transfers or Eurocheques.
The file register.txt included with this package has all
the details.
To encourage registration, some of the professional
features are only enabled during the evaluation period and
after registration. I believe I can trust every OS/2 user
to register this version if he or she uses these features.
If you don't use them a slimmed down version is available
for download at the WarpCalc homepage (see header), this
will save you at least $10 off the professional price.
New in this release (GUI v1.84 Pro + CLI v2.74)
===============================================
This update fixes an ugly bug in the CLI version affecting
national signs for multiplication, division and decimals.
The GUI version has received only small improvements,
mostly in the form of new built-in functions. Have a look
at the revised online documentation for details.

Future
======
The future is bright! However the degree of brightness
depends greatly on you and me. If you email any bugs,
comments and suggestions to the support address found in
the header of this readme and I will see to them.
Anyone who will or already has registered the OS/2 version
and is interested in the upcoming version for the new Be
operating system (the BeOS) will get one free of charge.
Documenting the CLI version (v2.74)
===================================
The command line version can be passed a mathematical
expression as a command line argument like this:
calc pi
The above command evaluates the name pi and displays the
result using default settings. It then immediately returns
to the command prompt.
It is also possible to enter more than one expression at
once, separating the different expressions with semicolons.
calc "x= atan 2; sin x/cos x; tan x - ans"
The first expression assigns the angle for tangens 2 to x.
In the following expression the value of x is used to
calculate tangens for x. The last expression should give
the result zero (ans holds the result from the previous
expression).
When starting the command line version without passing any
expressions the program will display a command prompt. From
that prompt you can evaluate mathematical expressions and
configure the calculators behaviour. The prompt shows the
angular unit currently used. Online help can be displayed
by entering the internal command 'help'. For a list of
help topics enter: 'help ?'.
As a default the calculator uses a flexible result notation.
Except for fix point notation the default precision is 15
significant digits (fix point notation uses 15 decimals).
The default angle measurement unit used in conjunction with
the trigonometric functions is radian. The defaults can be
overridden through command line options as shown below.
[ /not sci|fix|eng ][ /prec <n> ][ /unit deg|rad|gra ]
To have the calculator use ANSI colors to highlight input
and results add the following switch.
[ /color ]
For U.S. based users there is also a switch to force the
calculator to use ISO signs for decimal separator,
multiplication and the division.
[ /iso ]
Defaults for the command line switches can be set through
the following environment variables: calc_not, calc_prec,
calc_unit, calc_iso and calc_color. The options are the same
as above except for calc_iso and calc_color, which take
either a yes or a no. All environment variables are case
insensitive.
The internal command line works as follows. A block cursor
indicates over-write mode and a line cursor insert mode.
Escape erases the current input. Input history can be
navigated with the up/down- keys.
For registered users of WarpCalc Pro there is an enhanced
version available upon request. Email delivery is free.
This version recognizes sexagesimals and has selectable
base mode among other things. Unless you state otherwise
you will receive updates as they become available.
