- 1- DESCRIPTION
-
- You hold in your virtual hands (on the computer screen) version 1.1 of the
- Metric Conversion Calculator (MCC). This program allows simple calculator
- functions, and conversion between the numbers on the display and a
- wide variety of units in the metric and non-metric (imperial?) systems
- of measurements.
-
- To run MCC 1.1 you will need:
- - Windows 3.1
- - the file vb40016.dll in your Windows\System directory
- (NOT included with this package, but it is available from the better
- download sites or from Microsoft free of charge)
- - a video display (no minimum requirement)
- - 1 MB of free memory
- (the program itself takes 40K, but vb40016.dll may require more elbowroom
- than that.)
- - a compatible input device like a mouse or touchpad.
-
- To run the program, do the following steps:
- - ensure you have all the above requirements met in your system
- - place the executable (calc1_1.exe) in a directory on your hard drive, or
- run the program from a floppy diskette.
- - From the File Manager, double click on the calc1_1.exe filename.
- - OR From the Program Manager, click on the File menu and select the
- Run option, then enter the drive and directory path name and the executable
- name, example: C:\windows\utils\calc1_1.exe
- - OR Create a new program item in a group in the Program Manager and double
- click on the new icon (see the Windows manual for instructions on how to do so)

- 2- SUMMARY OF FEATURES
-
- MCC 1.1 allows basic mathematical operations to be done, letting it work as a
- simple calculator. To enter numbers into the display box at the top of the
- main screen, there are two options: type the numbers with the keyboard, or
- click on the appropriate buttons on the display. Valid keyboard input
- includes the digits 0-9 and the decimal point, while the screen also includes
- buttons to switch the value between negative and positive values.
-
- Once the number has been entered in the display box, you can perform simple
- mathematical operations on it. MCC provides buttons for addition, subtraction,
- multiplication, and division, all of which are accessible both from the
- keyboard (strangely enough, using the "+", "-", "*", and "/" keys) and from
- buttons on the screen. There is also an Inverse function, available only
- on the screen with the button labeled "1/X".
-
- In the lower right-hand corner of the main screen, there are other simple
- options that are only accessible by clicking on the buttons on the screen
- (or alternately using the TAB key to cycle to them and pressing ENTER). These
- options include the following items:
- - Clear, resets the display and the pending operations to the neutral initial
- state, ie the display reverts to blank. Use the button labeled "C"
- - Clear Entry, erases the current value in the display but keeps pending
- operations, with the button labeled "CE". For example, enter 6 + 5 and then
- hit the Clear Entry button. The display reverts to blank. Then enter 1
- and hit "=". The display now shows 7 (that is 6 + 1)
- - Memory Set, which stores the current display in memory for later retrieval.
- This button is marked "Ms"
- - Memory Clear, which erases the value in memory. This button is labeled "Mc"
- - Memory Return, which re-displays the value that has been stored in the
- hidden memory, just by pressing the button labeled "Mr"
- - Memory Add, which adds the value in the current display to the memory value,
- without changing the display value. Use the button "M+" for this.
-
- The above features provide basic, simple calculator functionality. But the
- while point of this system is to provide the capability to see how much this
- would be in another measurement unit and system. To do this, you must
- identify the units you are working with. Click on the button marked "Set
- Units" to call up a dialogue box with lots and lots of units from which to
- select. The default unit every time you run the system is <None>, which
- obviously has nothing into which you might convert it. But in the Units
- dialogue box, you get to select among temperature, volume, area, distance and
- weight divisions, with metric units listed on the left of each division and
- on the right are the non-metric or imperial or US measures. Select one
- unit from the entire set of options and click OK, or Cancel to leave without
- changing the current selection. Whatever unit is selected will appear beside
- the display box on the main calculator screen, and the Show button will have
- its label and accessibility updated accordingly.
-
- If there are no units selected (ie "<None>"), the Show button will be disabled.
- Otherwise, the button will be able to be clicked, and will pop up a screen
- with the value and currently selected units displayed in bold at the top of
- the screen, and the converted units in plain font beneath it. There may
- be as few as one line (eg Celsius to Fahrenheit) or up to 6 lines in
- calculating non-metric distance measures. The raw numbers are displayed
- in this Conversions box, just as they are calculated, meaning they may have
- many decimal places, or they may have automatically switched to scientific
- notation if the number is too large or too small. There is a button labeled
- "Cleanup" at the bottom of the dialogue box, which formats the values in the
- display into a more visually pleasing format. Currently this means that
- commas are inserted between every 3 digits, and the decimal part is rounded
- to at most 3 places. If demand is strong enough, I will give the person
- using MCC 1.1 more control over the number of decimal places to include
- and other formatting things.

- 3- REGISTRATION
-
- Metric Conversion Calculator is written as shareware. That means I encourage
- you to pass it on to all your friends and use it for free for a limited trial
- period of 1 month. After that time, I request that you either stop using
- it or delete it from your system, OR PREFERABLY send me the registration
- fee. It is a reasonable $10 for version 1.1, and will encourage me to keep
- creating new software and to listen to your bug reports and suggestions for
- improvement. It also means I will let you register any other of my program
- creations for HALF the requested registration fee, as a valuable repeat
- customer! See register.txt for more details.
