- <h2>Glossary</h2>
-
- <blockquote>
- <p><strong>Button:</strong> A rectangular area on the screen
- that performs a function. Note that keyboard keys are NOT
- buttons.</p>
- <p><strong>Display: </strong>The area of the screen that
- shows what digits have been entered, or the result of a
- calculation.</p>
- <p><strong>Formula Screen: </strong>This is a special screen
- set up to calculate a formula. Examples might be a conversion
- from Celsius to Fahrenheit, or a loan calculation.</p>
- <p><strong>Function: </strong>Functions are operations that
- the program can do, such as saving a variable, executing a
- macro, or adding two numbers together. Macros and layouts are
- built from functions.</p>
- <p><strong>Function Library:</strong> Applications written
- for the Applian Software System make use of a special DLL
- called a function library. Currently, the only available
- function library is coolcalc.dll, which is used for the
- CoolCalc program.</p>
- <p><strong>Layout:</strong> The arrangement of buttons on
- screen, as well as the properties and functions assigned to
- each button. A layout is stored as a series of commands in a
- macro file.</p>
- <p><strong>Macro:</strong> A series of button presses, stored
- in a file. Macros are used to assign a repetitive calculation
- to a single button. </p>
- <p><strong>Parameter: </strong>This is something that every
- function is given, although some functions can ignore this.
- For example, the _PlayMacro function takes a parameter that
- is the name of the macro to play, but the Sine function
- doesn't need any parameters, since it acts on the contents of
- the display.</p>
- <p><strong>Program Mode: </strong>When CoolCalc is in this
- mode, you can rearrange the size and position of buttons, as
- well as changing their properties.</p>
- <p><strong>RPN:</strong> RPN (which stands for "Reverse
- Polish Notation") is a system of doing calculations that
- was patented by Hewlett-Packard in the 1970s. As the name
- suggests, things are done a little backwards, but the end
- result is that complicated calculations become much simpler. </p>
- <p>RPN is different in a couple of ways. First of all, there
- is no equals button. To perform calculations, you
- "Enter" the numbers you wish to use in your
- calculations, then press the buttons for the operations. For
- example, to calculate 3+4, you press 3, then ENT, then 4,
- then +.</p>
- <p><strong>Run Mode: </strong>When CoolCalc is in this mode,
- the calculator behaves as you would expect. In order to
- program the calculator (with the exception of recording
- macros), you need to change into Program Mode.</p>
- <p><strong>Status Bar: </strong>An area of the screen,
- usually at the top. This shows the status of the calculator;
- i.e. Program Mode or Run Mode, whether a macro is being
- recorded, and other things.</p>
- <p><strong>Variables: </strong>These are places to store
- values. A variable always has a name and a value associated
- with it.</p>
