[comp.sys.mac.system] System 7.0 compatible stuff

so273208@seas.gwu.edu (Jens Johansen) (04/23/91)

In a recent MacWeek they discussed compatibility of existing applications
with System 7.0, and they had a small table listing compatible products
and incompatible products.  It was very short, though, so here's an idea:

Can we start the creation of a more complete table here on the net?  I'll
start the ball rolling (very slowly, since I'm not a beta tester) with the
following table:

   Compatible     |   Incompatible   |   Incompatible   |   Unknown compat.
   as of now      | upgrade expected | and totally dead |   status
___________________________________________________________________________
Word 3.02         | Norton Utils 1.0 | MacWrite 5.0     | virtually everything
Excel 2.2         | MacPaint 2.0     | older MacPaint   |        else
Word 4.0          | HyperCard 2.0    | older HyperCard  |

<add your bits here>

Thanks in advance,

Jens

  Why is HC 2.0 incompatible?  I've run it almost constantly for several
months in 24 and 32 bit mode with no trouble under 7.0a9, b1, and b4.

Are you sure about the HyperCard 2.0? I used it this morning with system 7.0f2
without any problem. Or maybe I was lucky did not hit the bomb place?

I think it would be most feasible to start a list of applications that are
NOT compatible, since nearly all of mine are, and that encompasses hundreds.
(Although there are a substantial number that run fine in 24-bit and not 32)

Well, I'm probably the only person who uses this particular app, but FullWrite
Professional 1.0.1 is fully compatible with System 7 (and I use it very exten-
sively and "harshly," if you will).

The above list has a number of inaccuracies in it (as do most quotes from
MacWeek).  Speaking just to the Claris items, MacPaint 2.0 is "Mostly
compatible" (Apple's term meaning that you should be no worse off running it
under 7.0 than under 6.0.7 and that any 7.0-specific bugs are both hidden
and minor), not "Incompatible, upgrade expected".  HyperCard 2.0 is also in
the "Mostly Compatible" category, and the upgrade is included in the 7.0
upgrade package (that's what the RI code in the compatibility checker means,
Replacement Included).  I thought it was a little irresponsible of MacWeek
to take a known incomplete and inaccurate database that Apple distributed
specifically to solicit updates and additions as a compatibility statement.
Do you know of a better way to get companies off their collective duffs and
have them submit information than to have inaccurate, negatively slanted
information in a "draft" document?

The only thing that such "dissemination" accomplishes is to raise the fear
level of the consumer, usually without reason.  The Compatibility Checker
stack is due to go "Golden" any day now.  That would give MacWeek a few weeks
to pre-publicize all the information that the _REAL_ stack contains, but
I guess that sensationalism is more important to them.

READ MY DISCLAIMER BELOW, IT IS ESPECIALLY PERTINENT TO THIS POSTING!

You need to add more columns to your table.  Does "incompatible" means
"incompatible under VM," "incompatible in 32-bit mode," or "incompatible 
even with VM and 32-bit addressing turned off." 

hp48sx@wuarchive.wustl.edu (HP48SX Archive Maintainer) (04/25/91)

NISUS 3.05 is NOT completely compatibole with 7.0f2
You can't redefine command-key combinations, as all menus are greyed out
when the selection dialog is in front :^(

I guess system 7.0 will clean up in the world of software pirates :^)
most older pirated software can't run, and can't be upgraded. This is
good news for software houses and resllers.

I use FullWrite 1.5, and it has at least one problem with 7.0b4.  If
you try to set columns (click to "Set Margins" button in the Page
Setup dialog) the dialog which normally appears does not.  The menus
are disabled, and Fullwrite acts as though the dialog is there, but it
isn't.  Command-period will back out of this state, but you can't set
the margins.

That's interesting. Ashton-Tate is planning to update the current version 
of FullWrite (1.5s) to 1.6 when System 7.0 is released.

This is why this kind of "on the net" listing is so silly and unreliable.

So FWP 1.0.1 supports apple events? subscribe and the edition manager?
Aliases? 7.0 stationery?

Look -- the ONLY people who know whether an application is compatible with
7.0 is the vendor. Even Apple doesn't -- we don't have the time or the
energy to exhaustively test everything out there, which is why 7.0's been as
widely ditributed to the developer world as it was. 

If someone posts "foo is compatible" on USENET, all that REALLY means is "I
haven't crashed it on my system". The same with "Foo crashes badly" -- all
that means is that it doesn't work with that person's specific
configuration.

That information is useful in some ways, but keep it in perspective. Just
because program foo works on my MacII with 8 meg doesn't mean it's going to
work on a IIsi with internal monitor, 32 bit quickdraw and 17 meg, or a IIfx
in 32 bit mode with 16 megs of RAM and an 8x24 card with a 2 page monitor. 

Just because a program crashes in one place doesn't mean much -- it might
have been corrupted software, or a specific set of unhappy inits (um,
extenions) or whatever. Or maybe it IS incompatible. Without exhaustive
testing on a large number of configurations, you don't knw. It's all rumor
and hearsay. 

Now, none of this means that simply because the vendor says you need a new
version means you really need it. If it's not crahsing -- great. Perhaps
they're just adding the new functionality like publish/subscribe or events.
Or pe3rhaps you're just not running into the bugs because you don't have
16Meg of RAM and are running in 32bit mode. It just means it's not crashing
for you. Great.

So keep the stuff you hear, evne from us dweebs from Apple, in perspective.
The ONLY voice of authority on this is the vendor for each product. Anything
you see from any other source -- the net, MacLeak, your neighbor's poodle --
is going to be incomplete, inaccurate, based on simplistic and unexhaustive
testing and probably out of date. Use it with caution.

You've probably run into a problem with some XCMD/XFNC, I use HC 2.0 (and
so does most of apple) under 7.0 with no problems, except on some
stacks with buggy XCMD/XFNCs.

There's a 32 bit mode related bug when the System's WDEF gets purged.  So,
you'll see this one only when in 32 bit mode and after the WDEF was purged.

(lots more flaming deleted)

Thanks for the lecture, Chuq. Too bad you're flaming the wrong guy. If 
you'll look at my post that you quoted, you'll see that I was quoting 
someone else who said that FWP 1.0.1 was fully compatible with 7.0. I 
haven't seen anything "fully compatible" (publish/subscribe, AppleEvents, 
etc.) yet and don't expect to until autumn, although I'm sure I'll be 
reading all about such programs in a couple of weeks.

My only contribution in this matter was to mention that I had read (in the 
7.0 compatibility checker, I think) that Ashton-Tate would be releasing 
FullWrite 1.6 for use under System 7.0. I don't know whether it makes use 
of 7.0 features or if it's just a bug fix. I imagine I'll find out 
sometime after May 13.

Next time you decide to make someone look like an idiot on the net, check 
the details before you flame. I hope you "dweebs at Apple" are a little 
more careful with your programming than with your flaming. I'd hate to 
feel I had to wait for System 7.0.1 before I could safely upgrade my 
machines.

It has the same problem with 6.0.7.

That is not a system 7 specific bug. The problem is that FW checks the location
of the page-setup window using port^.portBits.bounds. Unfortuantely, this
assumes that the page setup window is a black and white window. Under System 7
the LaserWriter ( and probably ImageWriter, et. al. ) use color windows for
page-setup and print dialogs, so FW gets a bogus rectangle for the location
of the window, and centers the "Margins" dialog in some random place
( usually off the screen ). If you have a two-page display, you can sometimes
see the dialog. So, the dialog is there, just off the screen.

Now that the problem has been identified, someone can easily fix it with
a binary patch. I still use FullWrite 1.0 (and I use it quite a lot) and
it also has that problem. I'll probably try to patch it the next time I
need the set margins dialog.

The easiest fix would be to write an FKEY that moves the front window onto
the main screen. Running this FKEY would then make the invisible dialog
visible.

To patch FullWrite itself, one has to drop into the debugger at the
correct spot (easy to detect with TMON) make changes to the code
resource, call ChangedResource and WriteResource on the CODE resource
that was changed. This will make the application slightly larger,
because FullWrite compresses most CODE resources. Fortunately it
checks for the compression, so writing the uncompressed resource
doesn't make it malfunction.

I've done some FullWrite binary patching a few years ago. The FKEY
solution is by far the easiest and as such I recommend it.

Actually, I just noticed I had some time on my hands, so I wrote the
FKEY for you. It took me 15 minutes and it seems to work with everything
I tried (a few applications), so it's not really FullWrite-specific.
The Set Margins dialog works now beautifully.

I'm including the source code and a very short BinHex file with this
message. Use ResEdit to paste this resource into your copy of FullWrite
and hit cmd-shift-8 after the Set Margins button. Voila!

Think C source:
void	main()
{
	GrafPort	DummyPort;
	Rect		MainScreen;
	WindowPtr	FunkyFront;
	Point		Movement;
	
	OpenPort(&DummyPort);
	MainScreen = DummyPort.portBits.bounds;
	ClosePort(&DummyPort);
	
	FunkyFront = FrontWindow();
	
	Movement.h = (MainScreen.right-MainScreen.left
		      -FunkyFront->portRect.right+FunkyFront->portRect.left)/2;
	Movement.v = (MainScreen.bottom-MainScreen.top
		      -FunkyFront->portRect.bottom+FunkyFront->portRect.top)/2;
	MoveWindow(FunkyFront,Movement.h,Movement.v,0);
}

(This file must be converted with BinHex 4.0)

While we're on the subject of compatability...
I have heard rumors that only certain hard disk drivers will be compatable
with System 7.0 virtual memory. Since I don't use a hard drive that the 
Apple utilities will recognize, this is a concern. Has anyone ran across	drivers that will not work?
                  Thanks,

I can verify that Silverlining DOES work, and very nicely.  If you happen to be
using the Apple HD Setup drivers, you are told (upon trying to start up VM)
that you need to re-run the new 7.0 Apple HD Setup to enable VM.

The earlier (than 7.0) Apple drivers.  SilverLining drivers appear to work.
Apple's 7.0 HD SC utility crashes with virtual memory on.

The issue with hd drivers is that they have to be re-entrant. If you
get a page fault during a file system access the driver has to be able
to cope.
 
Silverlining 5.28 works fine for me. Check with your driver
manufacturer whether their driver is re-entrant.
