It sounds like Chuq could use a field in each card or background with
the first line holding the number of linked cards and the names or  id
numbers of the linked cards in the following lines of the field, but
this brings up a problem that I've been having:

I'm trying to go to cards by a name composed of a string constant and a
variable number, as in

  go to card "Sheetnum"&snum    -- and variants, incl. putting "x"&y in parens

but Hypercard usually fails to go to the proper, or any, card. This
occurs only (or primarily) in scripts; if I execute the same line in the
message window, Hypercard takes me to the proper card without
complaining.  Have I overlooked some requirement of the go command, or
can anyone suggest some other likely oversight on my  part?

I may be wrong (it's happened before :-)), but I think you may need to
set the cliping region of the current grafport with ClipRect(); that may
help.

This is one case where using LightspeedC does you no good. :-)

If a Mac program bombs under A/UX and its toolbox, is that a sure sign
that the Mac program is doing something that might cause it to fail
under future pure-Macintosh-OS environments (for instance, a MultiFinder
that uses the PMMU)?  What about under the release (gamma?) A/UX when it
exists?

>From: James Spohrer <spohrer-james>

Problem: You want to click on a word in a text field and have that event
send you to a new card.

Solution1: (Messy) - Write a line lexer that finds the rectangle for
each word in the line until it finds the rectangle that was clicked in.

Solution2: (Easier, but...) - In developing a mini-code browser, the
following was used satisfactorily: Select the word that you wanted to
click on by dragging across it in the text field. Define a button called
GOTO above the text-field. Click the GOTO button, at it takes you to the
documentation for that word, if you have a script associated with the
button like the following:

on mouseUp
 find the Selection in field "Documentation-for-Word"
end mouseUp

In your documentation cards, give them each a name field called
Documentation-for-Word, and put the word's name in that text field.

So instead of clicking on the word, you have to Select the word by
dragging, and then click the GOTO button.

Thanks to Stan Letovsky and Charlie Martin for parts of the "solutions".

P.S. I would like to hear alternative solutions.

Perhaps it is the standard practice in Canada, but not here.  And if it
is standard, there should be a warning anyway for those who are buying
their first program  (Apple doesn't do it). I have quite a few programs,
but this is the first one I have seen like this.  What is more, Semantic
Microsystems never did this on previous releases.  After the drive was
removed, the problem was apparent: the lever arm that opens the slide is
a piece of flimsy sheet metal and is easily bent; fortunately, not to
hard to fix.  It doesn't take much force to bend the lever, and thus the
drive design is also at fault.  The folks at Semantic Microsystems were
very nice, and I do not want to denigrate their company, which I like.
They are discontinuing the practice of putting stickers on the slide,
since this has happened to others too.  They offered to pay for fixing
the drive, but since we have an in-house technician, it was not
necessary.

Here's another one that should be a no-brainer, but the information
doesn't seem to be in the Goodman book. I want to have a line on one of
my cards that says "card #<num> of <num>". I can find the second value,
the total number of cards. I can't find any documentation for getting
what card number this is. Goodman simply says "since cards can be
re-arranged, use the card id and not that card number" -- well, I WANT
that card number.

Any idea what the variable for this it?

Date: 30 Sep 87 19:11:00 GMT
Organization: Digital Equipment Corporation


        I bought a Xerox/Nutmeg full screen monitor at Mac World in
        Boston. I like the thing. It is 720 x 900 pixels (8 x 10 inches
        at 90 dpi). Most things work quite well with it, notably Word
        3.01 (in which Page preview is gorgeous -- it uses the whole
        screen and gives you a nice legible picture), Lightspeed Pascal,
        and Superpaint. Hypercard centers its window in the middle of
        the screen, leaving lots of space for tools &c. Macsbug even
        works.

        You start up the screen with an application. I'd much prefer an
        INIT file, but you can't have everything, I suppose. It doesn't
        seem to consume much memory. I've gone prowling with Heapshow
        and MacNosy, and not found the nutmeg code (not that I've tried
        that hard), and I don't notice much less memory. The screen
        memory itself seems to be on the interface card (which is a
        clear plastic thing that slips over the CPU of a Plus or SE. I
        can't imagine it working any other way.

        The phosphor is a soft white with a bit of a yellow cast to it.
        A nice, friendly, *paper-colored* phosphor. I'm no fan of amber
        screens, but the more I stare at this screen the more I like the
        phosphor. It is also *very* long-lived, and there is essentially
        zero flicker (I'm a bit sensitive to flicker). I like the look
        of the screen better than any of the other screens I looked at
        (Radius, Megascreen, and a couple others -- I spent most of Mac
        World looking at large screens with intent to buy).

        You can direct an application to the Mac's screen by holding
        down the command key while the application launches (this also
        works for the Finder when you leave an application).

        Most applications that aren't smart about the large screen
        simply put themselves in the upper left-hand corner of the
        screen and work normally. Often, I run these programs on the Mac
        screen, simply because I find all that empty real estate
        distracting.

        There are a few things that don't work:

        * Tempo crashes the system with an odd address trap if you start
        it on the nutmeg screen. If you start it on the Mac screen
        and switch to the nutmeg, it seems to work okay.

        * Switcher animation is broken. Period. Messes up the screen. It
        looks like some twit hard-coded the number 512 in it. I haven't
        tried Switcher without animation -- this is not because of the
        screen corruption, but because I'm scared of Switcher, as it has
        a tendency to crash. It's cost me work more times than I like. I
        developed this aversion to Switcher long before I got the large
        screen. I'm hoping for better with Multifinder.

        * Remove Autoblack from your system folder! This should be
        obvious, but I spent most of the first afternoon I had the
        thing wondering why it crashed. The nutmeg screen has its
        own screen saver, so you don't need it.

        All in all, I recommend it whole-heartedly. If you can find it
        for $995, then get it! It's wonderful. If both screen could be
        used at once (` la Radius), it would be even nicer, but hey...

It sounds as if you need a stack of stacks, not a stack of cards.  In
other words, you could have a bunch of stacks that belong to a
"superstack".  The background of the superstack should define forward
and backward buttons that allow navigating among the primary cards of
each aggregate stack.  The primary card of each aggregate stack should
define additional buttons enabling browsing through its cards.  You
could even put in a fast browse button.  Copy it from one of the
provided stacks if you don't know advanced HyperTalk.

To know how many cards are in a stack, you can define a button in its
primary card that performs a HyperTalk "domenu stack info".  This will
bring up the stack information menu.

Try browsing the provided stacks.  It's likely you'll find a similar
application.  You can copy this and use it as a template for developing
your own.  Have fun.

Cards in a HyperCard stack are linked in a linear fashion.  In other
words, there are no one-to-many relationships.  There's no problem with
attaching  the count of the number of cards in a string to a primary
card, but the other cards have a first/next order; they aren't arranged
in a fan-like set-up.

The card count can be part of a script attached to the primary card, but
you may find that you don't need it. A simpler strategy is to  put a
button on the primary card for each card in the list that you want to
reach directly from the primary card (i.e., not in first/next order).
There are two ways then to set up the transfer.  You can link the button
to the card or you can write a simple script attached to the button
which simply goes to the required card (either by name or ID#).
Personally, I prefer the latter, using names, because it requires fewer
changes as the stack changes.  My buttons all "go to card x", where x is
the name of card. This way, if I move things around in the stack I don't
have to worry about situations where links may become invalid. Card
names are more informative than id #'s; they form a sort of
self-documentation.

Hope this answers a few questions.  (?)

I was bitten once by a bug that may be causing your problem.  It seems
that OpenResFile does a _RecoverHandle on the string you pass it.  Of
course, if you pass an explicit string like "\pDesktop" there is no
handle!  My solution was to create a handle, copy the string to it and
pass the dereferenced handle.  Pretty ugly, but it worked.

However, the code always crashed on me and did not return an error so it
may not be your problem.

You folks are two for two so far, so I thought I'd toss another one at

I can't find a stack that uses radio buttons. As far as I can tell,
there is no documentation on using them in either Goodman's book or the
help stack (should I take this as a hint? I NEED radio buttons). Goodman
simply says "you need a big script to handle radio buttons" which is
stating the obvious without telling me anything.

I know what I need to do to handle a set of radio buttons properly. What
I don't know, and can't find any documentation on, is (1) how to query
the state of a radio button ("hi, are you checked?") and how to alter it
("hey, turn yourself on!"). Anyone know the magic incantation?

click at the clickloc

would go to one entry, but "white bread" is different and "egg white" is
separate from those two. Ideally I would like to  wave my hands and
instead of "it" I would have ThisWord, LastWord and NextWord to play

own definition of word, rather than using the Apple- defined delimiters.

Any help for me out there??

Just as other buttons, "the hilite of <button>" returns true or false.
The home stack card for setting user levels uses radio buttons as a

Hello,

   I just installed a MacBottom HD 144 (INTERNAL Hard disk) for my Mac
II.  It was very simple.  Place drive in place, mount with 2 screws and
plug power and SCSI cables in.  The SCSI cable is kind of hard to plug
in, due to it's  position in the box.  I had to take out the tray
holding the floppy drives to connect the cable.  This required removing
4 screws, plugging in the cables, then putting the screws back.

   The drive MUST be set to SCSI unit 0  (meaning-leave the jumper out!)
or devices on the external SCSI bus will not be seen.  PCPC says this is
an Apple 'feature' allowing a user to 'turn off' the external bus for
debugging a flakey drive.  I will buy that.

   Anyway I plugged it in, and it booted right up. I ran Disktimer II on
it and the numbers were 40/42/12.  Jasmine 80, for comparison was
52/59/19.  The drive comes with a 1:1 interleave factor, so is very
fast.

    Well, I recently got a Radius Accelerator installed into my Mac SE at
work, and I am impressed. Here are a few comments:

    Installation: Tricky, but workable. BEWARE: the metal edges on the
inside of the SE chassis are VERY VERY SHARP, and I cut up my left hand,
rather badly. Fortunately, I didn't leave any blood inside the machine,
which was a good thing. The SE's system board slides out easily, but
with the Accelerator in place, will not slide in. You have to work one
edge in, and then pry out one side of the chassis, and pop the board in.
Easier to do than it is to tell about it, but not much fun. It reminded
me of service old HyperDrive macs.

    Operation: Simple. You turn the SE on, and that's all there is to it.
If you hold down the mouse button when you turn on, you get a little
configuration panel, that lets you turn on or off the whole accelerator,
and also control whether the 68020 instruction cache is on, and
whetherthe built-in data cache is on. And you can ignore this step. You
can tell the board is installed at boot because it puts a little box in
the lower-left corner of the screen with "Radius Accelerator" in it, and
a chip labeled "68881" if the math chip is installed (mine does have the
'881).

    Performance: Amazing. If you're used to a Mac Plus or normal Mac SE,
there's nothing quite like it. I also have a Mac II at work, and I find
myself using the SE more. I ran a Dhrystone, and the Mac SE seems to be
about 8 percent faster than the Mac II. I'll post a detailed set of
benchmarks as soon as I run them.


Please note that this does not constitute a formal review, and this
posting was not solicited by anyone -- it's just that I haven't seen
much on this newsgroup about accelerator boards, and thought I might get
something  started...
