That's true for Original TOS and Mega TOS. For Rainbow TOS (TOS 1.4),
XXX need only be the number of folders you'll have "active" at once.
"Active" folders are those involved in file searches, open files, etc.
If you open a file, the folder it's in and all the parents of that
folder are "active;" if you open another file in the same directory,
you haven't increased the number of active folders. If you close both
files, those folders aren't "active" any more, and the space they took
up in the pool will be reused when necessary.

I saw a STacy ad in some magazine (Popular Science maybe, i'm
not sure which one) for a STacy. A single full page article and a picture
of a STacy. Looks pretty nice. Anybody else seen this ad?

There are some gulam parameters that can be set in a startup file.
They are called, I believe: 'set env_style <style>' where
style can be three separate flavors. (Here my memory is faulty about
the types, but I use 'gulam' style).
I don't know quite what this means, I don't recall reading a description
in the docs. Anyone know more about this?

env_style has nothing to do with this. env_style determines
how the environment variables are setup, and how the
command lines/environment programs are setup before a program is lauched
via Pexec(). the possible value are
'bk' beckemeyer
'gu' gulam
'mw' mark williams
gulam.doc talks about what each of these means.

huh? Dgetpath/gemdos whoever *does* monkey around in the buffer
you supply. if the buffer supplied to Dgetpath() is shorter than 32
bytes it clobbers stuff outside of it (my guess is that it has someting to do
with the fact that a directory entry is 32 bytes long) (i cant
remember exactly, but maybe you need to s/32/64/g above).
the developers gemdos documentation states that 125 is the max
path length. i guess its either obsolete or incorrect.
on a related note: gemdos(Fsfirst()) still (at T1.4) doesnt
realize that "." ".." "\" or "D:\" are directories (have attr == 0x10)
(or atleast "." and ".." should be, even if "\" is not considered to
be a subdir).

I have Aladin 3.0, and am a very satisfied user. It has the 64k roms.
It supports at least the SH204 and SH205, but also other drives that I
do not know of. It runs the mac software that I need.
Unfortunately, the Aladin people were forced out of business by an Apple
lawsuit threat a few months ago. So we won't have the 128k rom upgrade.
One of the Aladin people proposed a shareware version in this group,
but hasn't been heard of since.
>Anybody have any suggestions? (come out of that hideyhole, Europeans)
Here I am. We hear some good things about the Spectre. Try to take one
with you. I suppose they'll be cheaper over there. (Yes, I'm Dutch. So is

I have seen a friend of mine do it. He bought the part over the counter at
an electronics supply house. I believe Best Electronics has this part (and
others for the ST). If anyone has the address for this company, please post
it (I was told that they sell a cable kit for hooking a 5.25" drive to the ST).

TOS 1.4 will directly support 32M partitions; Supra's formatter probably
was written long before TOS 1.4 was. I have formatted 20 meg partitions with
Supra's formatter (because HDX 3.02 does not like something about my system,
and I strongly thing it's my DMA chip) no problems.
HDX 3.01/2 will let any Atari support reeeal big partitions.
While I'm here, can anyone tell me <again?> what the cutoff point for 512 byte
sectors is using HDX? A friend of mine formatted his Seagate 296N with his ICD
utilities (he has an ICD HA, of course), and used HDXPREP and then HDX to
partition the drive into four 20 meg partitions. His sector size is 1024 bytes.
Someone else said that the sector size stays at 512 bytes 'til you reach the
32M+1 region.

Mmm....definitely. Its hard finding good C source code for such GEM
applications. I don't know about its distribution in the US but the UK "ST
World" magazine has a "Programmer's Clinic" section each month, usually with a
fair amount of C in it. It might be worth looking at that.
How would this C source be made available? A new group? FTP? ??
No matter to me - I'd be interested in whatever form it takes.

The first thing that comes to mind here is that the compiler is not
converting j to an int before placing i and j on the stack. If this is
the case, and assuming i and j get put on the stack first, the stack would
look like this:
0x2000 (lsw of j)
0x0000 (msw of j)
0x2000 (i)
Then, when it goes to pull two ints off the stack, it gets 0x2000 (which
gets substituted for j) and 0x0000 (which gets substituted for i. Now, we have:
fprintf(stderr,"%lx, %lx\n", &(tab[0x0000]), &(tab[0x2000]) );
Now we have two different addresses that are offset by 0x2000 x sizeof(long)
if sizeof(long) == 8, that would explain the difference you got, but I thought
a long was 4 bytes... But this is how you could get different results by
passing the wrong size object, anyway. If you want to use a long as an
array index, try this:
#define tab(X) (*(tab + sizeof(long)*X))
Then you can do things like:
tab(100000L)=4567L;
printf("ADDR=%lx, VALUE=%ld\n",&tab(10000L),tab(10000L));
---jb
P.S. - I highly recommend turning on every warning that the compiler
supports, this will usually catch things like using longs as array
indeces, and other nasty litte oversights.
