Subject: How to identify an HFS disk?
Can someone tell me how the Macintosh differentiates between an MFS and
HFS disk? I am doing file recovery on damaged MacWrite 4.5 disks, but
when they are severely trashed, Fedit will treat two-sided disks as
one-sided only. What I want to do is change the bits of information
that identify a particular disk as being two-sided as opposed to one-sided.
This way, I'll be able to look at both sides of the disk.
So my questions boil down to:
1. Where is the HFS/MFS information stored? (In the boot blocks?)
2. What hex code sequence means HFS? MFS?
Any hints would be appreciated by both myself and the people I'm trying
to help.

Subject: Symbolic Debuggers for the Mac
I wonder if anyone knows if theres a compiler out there for either
"C" or Pascal that comes with a symbolic debugger. Not that I'm planning
to wimp out, mind you. Debugging disassembled machine code dosen't
scare me in the least, I think. But, it would seem that unless you are
exceptionally proficient at debugging complied code, a symbolic debugger
could really be a productivity boost.

[ note from moderator: Currently the only products I am aware of that have
a source level debugger SHIPPING with them are Microsoft Fortran and
Lightspeed PASCAL. Evidently Aztec C is planning a source level debugger
by the end of the year but it is not available yet. DAVEG ]

Subject: Re: Interlace and Dbase Mac
I was not surprised at all to see such a diagram, since it has appeared
in roughly the same form in just about every book on relational database
design ever published. Whenever the concept of joins is explained, the
typical diagram which Interlace and DBase Mac use is brought into play.
There may even be such a diagram in the original DBase II manual.
What seems to be copying at first glance is probably just a concession
to the standard notation scheme.

Subject: Smalltalk
A new version of Smalltalk (version 0.3) has been listed as being available
from APDA. This version is being released under the same terms and conditions
as Smalltalk version 0.2. The description for the new version is:
"A new version for the Mac Plus but can be used with an XL or any other
Macintosh with at least 1MB of RAM. A hard disk is recommended. It
contains many new features and enhancements not included in v. 0.2,
including faster window updates and HFS support. $50.00"
Sounds great to me!! Also, I just finished working out all the examples
from 'A taste of Smalltalk' and I would recommend it to anyone wanting to
learn or play with Smalltalk.
To order from APDA, you must be a member ($20/year) and you can get details
via: Apple Programmer's & Developer's Association

Subject: New TML Pascal
TML Pascal version 2.0 is out, and it looks super, and I am going to get my
update! Full (as defined by Apple & Wirth) Object Pascal, separate compilation,
>>and<< long array addressing!
Lightspeed Pascal is pretty in most respects, but I don't like the linker at
all, after using TML's linker. The code it produces is too fat. But since TML
and Lightspeed are reasonably compatible, I can use LSP to develop my application
and TML to crank out the final product...

This Hqx contains the files needed to implement a dumb printf()
debugging window
in LightSpeed C. I haven't tried it yet, but it looks interesting. From
CompuServe.

Subject: form
Here is a Macwrite version of the information and application form about
Apple's new APDA, the Apple programmers and Developers Association. It was
announced at macExpo, and is going to be a single source for all those Apple
things you never knew where to get. Looks great, everyone working with the
Mac should join it!

Has anyone yet heard anything about Mactran 77, a rumored 2nd Fortran
77 compiler for the Mac?

Subject: Information needed on Laser Printer Cartridge refilling.
My problem is that we have two LASER printers now working in this CSIRO
Division and consequently are using up quite a lot of Laser printer
cartridges. I have notices in the network mail that companies in the
US are not refilling Laser printer cartridges. Can anyone tell me if
such a service exists in Australia (here's a good opportunity for someone
with a business flare!) or is about to start.
My address is given below. Could people contact me there please.
Best wishes. Raymond Haynes:
