- MathPad 1.3, Copyright (C) 1993 by Duane Bailey
-
-
- Requirements: IBM PC or compatible, 80286 or higher microprocessor
- 80x25 display (80 columns by 25 rows)
- probably needs DOS 2.1 or higher.
- A maximum of about 112,000 bytes of free RAM is all I need.
-
- I recommend: A hard drive
- Color display (makes any color program easier to understand).

- Most of the help you'll probably need comes up every time you choose a
- subroutine, except for subroutines 1 thru 10, where you compute the volume or
- radius of a right circular cylinder. Say you choose F, "surfsphr". Well, the
- algebra involved first must compute the radius, because radius is always what
- circles are based on. So you enter the surface area of your sphere in
- "square" units. You first get the automatic readout of the other measurements
- of your sphere. Then you get a prompt to enter a height for a right circular
- cylinder. This cylinder has the same diameter as the sphere. The file
- "CYLINDER.EXE" can illustrate this. The picture supposes that the cylinder is
- transparent. It is a side view. The height could also be less than the
- diameter. Same for a right circular cone. Press a key to exit the picture. If
- you need more help, mail questions to me. I can offer phone support only to
- registered users. For the 10 programs which use Pi, I have plugged in Pi
- accurate to 19 decimal places, which is 3.1415926535897932385. This package
- can be registered for $10.00. This software is copyrighted! If you keep it,
- you must send me $10.00 check or money order. Then I can keep you on record
- for special deals on other software I make. (See registration information at
- the end of this document).

- A scientific calculator can be had for about 17 to 20 dollars these days, and
- they can do a few things MathPad can't. Correspondingly, MathPad can do some
- things a calculator can't. With how many calculators can you dump 15 numbers
- into the register at once, press a key, and it adds or multiplies them? How
- about enter any one thing computable about a circle or sphere and instantly
- find out everything else computable about it. And a calculator can't keep a
- text log file viewable at leisure and printable on a printer. So it's a
- trade-off, actually you need both, and you're only 30 dollars behind.
-
-
- The log file: If you decide to keep a log file, MathPad asks you to name it.
- Any valid DOS path and/or file name goes. Be careful not to name a log file
- the same thing next time you use MathPad without first viewing, making use
- of, or moving or renaming the previous one or whatever, because it would be
- overwritten according to standard DOS rules. It is a "plain-Jane" ASCII text
- file, and its contents are self-explanatory and easy to understand.
-
-
- To set up MathPad as a Windows 3.x application: Highlight the -group- called
- Applications. A bar will appear across the top. From Program Manager, choose
- File New. Choose Program Item. For the description type MathPad. For the
- path, that's up to you where you keep MathPad, but the executable file is
- MathPad.Exe. So for your command line you might type in something like
- C:\MATHPAD\MP.EXE. You click OK once or twice, and Windows gives you a
- generic icon. Click once on the icon to highlight it, then choose File,
- Properties, Change Icon. Windows will probably tell you no new icon is
- available. Ignore this, click OK, and just start typing something like
- C:\MATHPAD\MATHPAD.ICO, a file I have provided. Click OK a couple times.

- Note that the program counts your entries, -except- when you make some sort
- of input error. When this happens, you'll get a text message instead of a
- number answer. These errors are not counted. There is -one- exception,
- however, in the one named "quadrati" (choice Q). If you get a message saying
- that your solution set is empty, that entry is counted as valid, since if you
- knew your problem had no real solutions, you wouldn't need my program! This
- is the only case when an entry that results in text instead of numbers is
- counted. Note also that in the three temperature conversion choices, (K, L,
- M) that if you enter a temperature too low, you get a message. These aren't
- counted. If you want to know the lowest possible temperature that can exist
- (absolute zero), enter zero for kelvin. Usually in nature the coldest places
- in the universe are at about 2.7 degrees k. Note also that a kelvin degree is
- the same unit size as Celsius, but offset by 273.15 degrees k (or c).

- MathPad is an outgrowth of my previous shareware number-cruncher: "MyMath".
- It consisted of no less than 22 executables, and it ran stick, baling wire,
- and gum fashion by a long batch file. Its approximate length on disk,
- compressed, was about 150 KB. Uncompressed it was about 250 KB long! The
- uncompressed program file MP.EXE is only about 105 KB long. If yours is
- smaller, it's been compressed. It expands in RAM when run. If you ever used
- "MyMath", you may remember that the only logging function available was
- Ctrl-PrintScreen. The days of those horrors are long gone. (See "The log
- file", above, line 46 of page 1). "MyMath" will go the way of masterpieces
- like Edlin and Algol-68 (flowers and "Taps", please).
-
-
- I am author of all files. If you distribute this software, you must always
- include -ALL- files;
-
- They are: "MP.EXE", "MATHPAD.DOC", "MATHPAD.ICO", "SCIENCE.WRI", and
- "CYLINDER.EXE". No-one may collect more than $3.00, and you must inform the
- person that it's only a "disk charge". You must also inform them that if they
- keep the program after 30 days evaluation, they must mail me $10.00 check or
- money order. Professional shareware distributors: If you can't sneak in at
- $3.00 or under before tax, you can't distribute MathPad. (And you need to
- visit a reformed man named Scrooge for advice). MathPad may be included with
- other shareware as long as all five files are present and unaltered. I will
- be concentrating on distribution mainly by bulletin boards, which skips the
- middleman and saves people up to 3 of their hard earned dollars.
-
-
- Registration entitles a person to:
- Phone support (on their nickel), "almost free" upgrades, (I would compute the
- exact price of the diskette and postage, and charge only that, in order to
- break even). Notices of other programs I write, and 20% off on those if you
- buy. This is for registered users only. So if John Doe writes the check for
- MathPad, and his daughter wants some program I write in the future, and she
- did not register MathPad too, she does not get 20% off. But if she registers
- the new program, then she gets 20% off of any other program I write (and that
- includes MathPad 1.3, this program). Please don't send cash. I can accept
- only checks or money orders. I am not authorized to accept credit card
- numbers either.
-
-
- Site usage of MathPad:
- 1 to 5 copies: $10.00 each
- 6 to 10 copies: $ 8.00 each
- over 10 copies: $ 7.00 each

-
- Dear Reader, April, 1993
-
-
-
- This is a book I have written and copyrighted. The material is about half
- scientific, and half human/Christian. The first half contains the science.
- This book is divided into 9 chapters. It is readable by Microsoft Windows 3.1
- or higher. (Windows "Write").
-
-
- I have set the margins for my own printer. If you need to adjust margins,
- adjust only left and right ones, and by the same amount each. (Where you see
- a new paragraph apparently shoved up against the previous one, look left and
- you will see the symbol >>. This is a page break. It insures the top margin
- will remain the same when a new paragraph also happens to start on a new
- page). Leave it "justified". Only 8.5" x 11" paper should be used. The page
- numbers are embedded and will appear at the bottom of the pages when printed.
- They don't appear on screen, however. The pages can be 3-punched and placed
- into an inexpensive 3-hole folder. A laser printer will give best results.
-
-
- How much is my book? Well, it represents 3 months of work in my spare time.
- Since I possess copyright, let's go by "shareware" rules. If you like it,
- $5.00 will do just fine. Then I will record you and keep you in mind for
- information about my future writings, and maybe a special deal on those.
