- TextCalc (c) 1990 John A. Samuels p 1 of 8
-
- Hi! TextCalc will allow you to load in any text file and do arithmetic
- calculations on any of the numbers in that text file. You're reading an
- ordinary text file right now. Just follow the directions...
-
- With the LEFT mouse button, click on this number: 123
-
- The number '123' should've shown up in two places - the string gadget titled
- "Left Button" and the string gadget titled "L Click Sum".
-
- Now, with the LEFT mouse button, click on this number: 456
-
- The number '456' should be in the "Left Button" string gadget and the number
- '579' should be in the "L Click Sum" string gadget. That's because '579' is
- what you get by adding '123' and '456'.
-
- To continue, click on the right arrow at the bottom of the screen...
- p 2 of 8
- Ok, that's how you get to the next "page" of your document.
-
- Now click on this number with the LEFT mouse button: 789
-
- Now '789' should be in the "Left Button" string gadget but the sum of 123
- plus 456 plus 789 should be in the "L Click Sum" string gadget. Cool, huh?
-
- In other words, each time you click on a number with the Left Mouse Button
- it's added to the number that's in the "L Click Sum" string gadget. The new
- total is placed in the "L Click Sum" string gadget and the number you clicked
- on is placed in the "Left Button" string gadget.
-
- Wait! There's much more...
-
-
-
- Click on the right arrow when you're ready to learn more...
- Ok, now we'll do some more math... p 3 of 8
-
- But first, let's clear all the previous stuff.
-
- Click on the "c" gadget that's to the right of the words "Left Button" under
- the "Left Button" string gadget. A '0' should show up in the gadget.
-
- Do the same thing for the "L Click Sum" gadget.
-
- Now, click on this number with the Left Button: 15
-
- And click on this number with the RIGHT Button: 25
-
- The number '15' should be in the "Left Button" string gadget and the number
- '25' should be in the "Right Button" string gadget.
-
-
- Click on the right arrow to get to the next screen...
- Ok, let's multiply our two numbers (15 and 25) together. p 4 of 8
-
- Click on the gadget that has the "X" in it. Notice an "*" shows up above the
- four "operations" gadgets. That means that until YOU say otherwise, we'll be
- performing multiplication.
-
- Now click on the big "=" gadget.
-
- The answer, '375' appears in both the "Result" string gadget and the "Running
- Total" string gadget.
-
- You've multiplied '15' times '25'. Nice going!
-
- Now click on the following number with the RIGHT button: 40
-
- It's in the "Right Button" window, right?
-
- Please click the right arrow to continue...
- p 5 of 8
- Ok, now click on the "=" gadget.
-
- The number in the "Result" string gadget changes to 600 (15 * 40) and the
- number in the "Running Total" string gadget changes to 975 which is the sum
- of the two previous multiplications that you've done.
-
- Let's review...
-
- o To put a number in the "Left Button" gadget, click on it with the Left
- Mouse Button. To put a number in the "Right Button" gadget, click on it
- with the RIGHT Mouse Button.
-
- o To perform an operation on the Left and Right numbers, click on the sign
- you want to use (+,-,*,/) , then click the "=" gadget.
-
-
- Please continue to next screen by clicking the right arrow...
- p 6 of 8
- o You don't need to choose a sign for each calculation.
- If you want to do, for instance, several multiplications, just click
- the multiplication gadget once. It stays on.
-
- And if you plan to use the same number for more than one calculation,
- there is no need to choose it (click on it) more than once.
-
- This makes calculations quick and easy.
-
- o Each time you click on a number with the Left Button, that number is
- added to the number that's in the "L Click Sum" gadget and the result is
- placed in the "L Click Sum" gadget.
-
- This makes it very quick to do addition.
-
-
- You know what to do to continue...
- p 7 of 8
- o Each time you click on the "=" gadget, the result of the
- calculation is added to the number that's in the "Running Total" gadget
- and the new result is placed in the "Running Total" gadget.
-
- Now, it's significant that there are all these "string gadgets" down there
- towards the bottom of the screen.
-
- You can type any number you want into any one of them. That number then
- becomes "active" and can participate in any calculations. That means that a
- number that you need to use does not have to be in the document you've loaded
- into TextCalc.
-
- In fact, if you so desire, you can type your dog's name or your favorite
- Portuguese swear word into one of them. The contents of that string gadget
- will then be evaluated as zero ("0") as will any non-numeric entry.
-
- Please go to the next page...
- p 8 of 8
- Lastly, TextCalc keeps a "log" of all of the activity it
- creates. This log is found in your RAM: directory. It's called "tc.log" and
- is an ASCII text file that can be read by any word processor or text editor.
- Of course, it can also be read by TextCalc so that you can perform
- calculations on your calculations. Got that?
-
- RAM:tc.log will be appended, not overwritten, each time you run TextCalc.
-
- Please read the text file in this archive called "read.me.later" for some
- important additional features and non-features. "read.me.later" is the
- complete documentation for TextCalc.
-
- Thanks for reading this. You won't regret it.
