      Bugs not reported are almost guaranteed to be included in the
      next release!

      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 (and later FixPaks
      for Warp 3).


      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 2.0 is freeware! The great thing about freeware is
      that you only pay for it if you can and wish to make some
      poor developer happy. Although in every way optional, you can 
      still get a personal licence for use with this version 
      (see register.txt for details).


      About this version
      ==================

      New: Freeware.

      Changed: Open Watcom C/C++ 1.9 has been used to compile and
      link this version.

      Changed: Versioning scheme consists of four fields: major
      and minor version numbers followed by revision/prerelease and
      stepping. The full version specification for this release is
      2.0.0.0.

      Changed: A new registration key is required. It is available
      for free for all previously registered users.

      More: See online help.

      Documenting the CLI version
      ===========================

      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 behavior. 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.

      [ set calc_pos= <column> ]

      By stating the above in config.sys or directly at an OS/2
      command prompt you tell the calculator what column position
      to use for the last digit of the results. The default,
      far right, position may be inappropriate when in fullscreen
      mode. To fix results at column 40 simply specify:

      set calc_pos=40

      Note that 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.
