      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.
