| I have caught the "Concept" virus a couple of times - apparently through
e-mail text, not a program. It attaches itself to MS Word .DOT template.
If you cut and paste text to e-mail and have the virus in your program
you might as well be French kissing as e-mailing.
I have had to clean up my hard drive 3 times using Mcafee. If you don't
have Mcafee, I heard that Microsoft has freeware at their web site.
If anyone else has caught "Concept," please post it so I can sleep at
night w/o wondering how I keep catching it.

Why not? I seem to have missed the beginning of this thread, so maybe
I'm missing some context, but if aDouble were the result of any kind of
operation[1] (i.e. other than "aDouble = DZERO"), I'd want to write
something like "if (fabs(aDouble) < FUZZ)". It's too bad VC++ doesn't
turn this into a single cheap x87 FABS instruction, but that's compilers
for you.
[1] well, if you know it's positive, for example, you could just test
"aDouble < FUZZ".
Anyway, mostly I wanted to respond to the subject line: I believe I've
run into a bug in the 5.0 code generator. Though I haven't tracked
down and isolated the problem, I have audio code that emits only zeros
with 5.0's optimization. It works unoptimized, with 4.2, or both.
I've heard of other people having problems. Hold out for 5.1, I'd say.
(Actually, my feeling is that you should never upgrade software without
a compelling reason and a good backup, but then I'm a known Unix user.)

Hello;
I wish to analyze some .WAV files with the hetro.exe utility
of Csound. I am not quite sure why but none of the .exe utils
will run on my WIN95 system. WinSound does however. Does
someone have a suggestion?
Thankyou
Andy A.
ada@skyenet.net
Symptom;
I open a DOS screen (full or reduced it makes no diff or even a DOS
boot) in W95 and run the hetro.exe + switches command line, what I
get in return is this.
'stub exec failed'
'dos4gw.exe'
'no such file or dir'

Can someone give me an example of a feedback loop?
Is that possible in csound or do you have to synthesize
a feedback loop like that?

hello csounders,
i am having an interesting "interchange of ideas" (a.k.a arguing) with
somebody through e-mail.
any help on this? here's part of his msg.

i'll be grateful for any info on the subject. you can e-mail me
privately if you prefer.
thanks in advance,

WELL! Isn't this yet another very good reason not to send mail other than by
simple ascii???? :-)

Yes: The optimizer in VC++ 5 was messed up for f/p operations. You have to
Install Microsoft's HUGE Service pack (now up to No 2) to restore things
to (almost) normal.
The discussion about texting against zero came up because I found a bug in which
a double initialized to zero got changed by the optimizer to NEGATIVE zero (!!),
which was enough to throw a text incorrectly.
