Let's compare apples to apples here...it makes sense to want 3 seperarte
items that perform their tasks perfectly than 1 item that performs 3 seperate
tasks half-ass.
Look at the list of software that wouldn't run on the Megas! You bought a
piece of software for an ancient IBM PC, it worked on a PS/2. period.
As for wives, the one you described is taken. :-)

There is something called FSCK that is available from panarthea.
You can get an index for panarthea by sending mail to
archive-server%panarthea.ebay@sun.com
and include this line:
index binaries
To get the file I think you want include this line:
binaries/volume3 fsck
To get instructions, include this line:
help

Malloc(-1L) does not return the amount of free memory available to the system
only the size of the largest contiguous block. If your memory is fragmented it
will return less than the true available memory.

Ugly hack that fragments allocated block structures!

Not available with stock malloc fuctions. Malloc is a VERY unreliable
memory manager and it is best to use the OS call as infrequently as
possible. The most elegant way to do it is to write your own malloc that
limit the total number of Malloc blocks to LESS than 16 and dynamically manage
those blocks as required. Find the source to some public domain C comiler if
you need a prototype for these types of routines.

Do you malloc() memory and change screens via Setscreen()? If you do,
you must be careful to save the original values of Logbase() and
Physbase(), and return to using them via another Setscreen() before
you exit. Otherwise, when your program exits, the memory you
malloc()'ed for your screen is freed, allowing it to be allocated by
other processes. If the desktop writes on the screen at the addresses
you left active, it can scribble all over the free-memory pool,
resulting in spectacular crashes.
As a general rule, one of the first things I create in each GEM
program is an initialization routine and a termination routine. These
share certain globals, such as the original values of Logbase() and
Physbase(), the initial palette, and so forth. Then I religiously
call my termination routine anywhere the program exits (such as within
fatal error handlers). This assures that things are put back the way
they were previously.
(Four bombs is an "illegal instruction" error. This suggests that
code in RAM is getting clobbered somehow. In my experience this
usually results from wild pointer references (storing through a
dereferenced, uninitialized pointer). Any code that does a malloc()
or close relative is suspect in that case.)

Good ol Uniterm 2.0e will do this and more. A very robust and powerful
program. Also, for about $15, one can buy Flash. It does NOT include
Kermit protocol, but there is a desktop accessory that gives it that
capability (which is either shareware or pd, I am not sure). I use
flash myself (without Kermit) because it is much easier to understand
for a novice (which I recently was). Also, it looks better on a color
monitor (IMHO). With a mono, Uniterm is stunning, allowing super teeny
tiny text as an option (really nice with big listings). Uniterm is free,
and probably the most capable and error free terminal program for the ST.

Check out Uniterm in the comp.binaries.atari.st archives on
terminator.cc.umich.edu ... Kermit support, full vt52, vt100, vt200, tek4010
emulation...great program.

Before you completely wipe out the Anti-virus you may want to make a copy of
the a disk with the AV on it and send it to the authors of VIRUSKIL so they
could inspect it and add it to the list of virus programs that their program
can defeat.
There was a discussion of anti-viruses a while back on the security mailing
list (or perhaps it was VIRUS-L) about anti-viruses and the consensus was that
anti-viruses are just as much an invasion of data privacy as any other virus,
inless intentionally installed (on your own media). Since these programs
exhibit all the same properties as other viruses (i.e. self-replication,
infection of disks that don't already contain the virus, etc.) they are just as
"bad" as any other virus (especially since it may really be a harmful virus
posing as an anti-virus, waiting for a certain signal to do some real damage.)
