- My daughter Suzi went blueberry picking yesterday, and I
- decided to get up early this morning and make some fresh blueberry muffins for
- the five of us for breakfast. I went digging through the recipe box for my
- favorite recipe. Wasn't there! (It was. I just didn't find it until much
- later this afternoon.)
- First, I panicked.
- How can I make my favorite recipe when the recipe has disappeared?
- Then, I paused and thought. As a teacher I should know better. I don't teach
- in the hope that the "recipe" will always be at hand for problem-solving.
- Hopefully, I teach problem-solving.
- Next, I asked myself What do I know? and What do I need to know?
- I discovered that I knew how to make the muffins: baking soda, flour, milk,
- blueberries, sugar, eggs, oil. And I remembered the logical amounts: 2
- teaspoons, two cups, one-and-a-quarter cups, lots, one-half cup, three, and
- one-quarter cup, respectively. And as I was remembering and doing, I kept
- recalling more and more of the process. Sift the dry stuff into a bowl. Make
- a well. Separate the whites and slightly beat them. Add the oil and milk.
- Stir until lumpy damp (my expression). Add the blueberries. Stir gently.
- Make dabs into pre-greased cupcake tins. Put on 4250 for about 20 minutes.
- Make coffee meanwhile. When done, wake family. Have good time with butter
- melting all over them. When all 18 are eaten, clean up.

- All of which brings me to a book I've had for a few months and have found
- useful, exciting, and full of fun: THE TI-99/4A IN BITS & BYTES edited by Remo
- A. Loreto ($14.95 from Remo A. Loreto, P.O. Box 14781, Cincinnati, Ohio,
- 45214). It's a book that's loaded with recipes (programs) but so full of other
- kinds of ideas that you will come away from the experience (if you put a lot of
- yourself into it) a baker (programmer). You'll learn so many logical, useful,
- delightful things about your TI that you will be able to create without the
- recipes and share your goodies with family and friends.

- Ten different programmers put their best digits
- forward in this large (8X11, 142 pages) book. The
- claim is that there are 50 programs in BITS & BYTES.
- Well, that's not quite true. First, they send you an
- extra program not in the book (which is quite good);
- then they don't count the small tutorial programs.
- There are 37 of these. So, though I bought the book
- expecting 50 programs, I ended up with 88! Pleasant
- surprise.
- Before discussing the 50 (51?) programs for which you
- buy the book, I'd like to talk about those other 37.
- The first 21 pages of the book take up these minis.
- Section 1 is a rather odd tutorial about programming
- commands made simple. I say "odd" because this is not
- a rehash of the manual which comes with the console.
- The tutorial assumes you're intelligent and that you've
- probably already read the manual. This section shows
- you ways to use CALL COLOR, CALL GCHAR, CALL JOYST,
- CALL KEY, CALL HCHAR & VCHAR, DIM, FOR-NEXT-STEP,
- GOSUB, GOTO, READ-DATA-RESTORE, and even PRINT in ways
- you may not have thought about.
- Section 2 is a really simple and good examination of
- flowcharting, including a more elaborate chart for a
- program in the back part of the book.
- Section 3 is a series of hints and tips. I was
- fascinated by this section and wished there were whole
- books devoted to this type of thing.
- Section 4 contains the 50 ready-to-run programs: 28
- are in BASIC, 23 are in Extended or require TEII. (If
- you noticed the mathematical disparity in the sentence
- above, I am including "Black Hole," the extra program.)
- These programs give you your money back many times
- over in pleasure. Although there are some practical
- programs for you serious types (such as Loan
- Calculating, Household Inventory, Curve Plot, Message
- Board) most of this wonderful book is full of games -
- GAMES! Oh, sure! Educational games are here, too, and
- there is nothing wrong with that. I'm a teacher, after
- all. But this book is mostly fun. Things like Space
- Fury, Trap, Skydiving, Eviel-Eyevil, Byteman, Death
- Mobile, Baseball, account for most of the 51 programs.
- If you enjoy typing in programs (which is one of the
- best ways of learning programming, so I suppose that -
- at least - is educational) then this book is for you. I
- thought the programs ran well and were quite good. They were also
- very easy to modify to your own purposes or tastes. I am very happy I bought
- this book, which, unfortunately, is not the case with some of the books I've
- purchased.
-
- Section 5 is an appendix that contains things programmers are always looking
- at: ASCII character codes, conversion tables, music frequencies, reproducible
- TI graph paper, and even a place for notes (which I find very handy).

- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Here's a small example from the book that shows you how to DISPLAY AT using
- BASIC:
- 100 CALL CLEAR
- 110 A=12
- 120 B=1
- 130 A$="TEXAS INSTRUMENTS HOME COMPUTER"
- 140 GOSUB 160
- 150 GOTO 150
- 160 FOR C=1 TO LEN(A$)
- 170 CALL HCHAR(A,B,ASC(SEG$(A$,C,1)))
- 180 B=B+1
- 190 NEXT C
- 200 RETURN
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
- But now for you non-typists, a super special treat. All the
- programs are available as a package book/disk or book/tape from some of the
- main suppliers of 99 stuff.
-
- While you're waiting for the book to come it, try my muffin recipe. You might
- enjoy that, too.
