I think it would be instructive for you to study the demise of Lucid, Inc.
and the way its founder, Richard P. Gabriel, was treated by the investors
(the _actual_ managers) of the company.
if a company fails, it's because of bad management. if it succeeds, it's
because of good employees. that is, companies with good employees and bad
management fail. companies with bad employees and good management fail.
the latter combination does not occur in practice.
however, more often than not, the whoever holds the purse is the actual
management of a company. and more often than not, people who make lots of
money are good at screwing people who trusted them, not at making good
technical decisions. (no, Bill Gates is not an exception to this rule.)
and if you make good technical decisions, you need a small, privately held
company to make it to manager.
a quick look at the Lisp industry will show you what kind of people lead
them, what kind of companies are really in this market, and also the
commonality of the failures. this is another reason I want to work with
Lisp. I don't want to deal with software companies that let people like
John Ousterhout do their marketing. (does that wrap this up? nah.)

Among other things. I think it had three or for lines of attack (finger
was one of them), and depended on overwriting part of the stack with
machine code (I think it was sending binaries for 3 or 4 different CPUs
and OSes, Novell probably not among them, but most likely VMS).

I presume "want to do a regex every time" means "want to match the same
regex throughout the lifetime of your program."
I have the same problem the original poster may have: I get a query,
build up a regex for the query, match potentially a *lot* of input
against the regex ... and then get another query, etc. I've left
comments about what code to put the eval "" around (a *big* honking
bunch of nested loops). I haven't done it yet; it's going to make the
application significantly harder to debug.
Note you need eval "", not eval {}; see MASTERING REGULAR EXPRESSIONS
for an explanation.
If you can generate a string you *know* will be matched by the regex,
you can say:
$string =~ /$tmp/ or die "didn't reset the default regex";
while (<INFILE>) {
if (//) { # match previous regex
do something;
}
}
But it's virtually impossible to create such a string.

This is the most curious construct I've seen in a long time. How does
the smiley qualify the 'asshole'? "Well, I just compared you to my
unwiped bottom and insulted your mother, but hey, why don't you come on
over for Sunday dinner?" Is this a new kind of doublespeak? Do you think
Dilbert gets letters from his boss that start with, "Dear Useless
Employee :)"? If two smileys were included after the 'asshole' would it
bring the whole thing up to the level of quite a nice compliment?
I'm baffled.
Mike.
(To Kevin: RELAX! You got some excellent advice from Tom. You can learn
way more by exposing yourself to the high quality code in CGI.pm or the
LWP family than by trying to code it yourself in isolation.)

Lay off. You have just asked the most fricking frequently asked
question in the history of this newsgroup, and it has nothing to do
with Perl. You are recreating a wheel that's already been done a
zillion times, and you have the same bugs that about a zillion minus
three implementations have used. Why do you expect the volunteers of
this group to spend laborious hours typing in the same answer to the
same question for every person who uses this broken code? Don't you
think it much better to point them to a solution that works? Did you
look at Alta Vista and Deja News for previous treatments of this matter?
Have you read the Perl FAQ? What about the CGI FAQ? Did you read the
Idiot's Guide mentioned in Section 9 of the Perl FAQ? Did you look at
the existing solutions to see what they were doing that you weren't?
How much effort did you put in to help yourself? Now, given that, you
still expect us to painstakingly debug your broken code such as has been
done hundreds of times in the past?
Why?

I absolutely agree.
This "MIT" attitude has continued to linger.
But if I have my way, those days are OVER.
The view that Lisp must be an order of magnitude better to win,
ends up with making it be an order of magnitude more complex,
and those who don't need nor understand this complexity are viewed as
"not worthy" --- is it any wonder why Lisp won't be widely used?
If one reads my first CLOS column in JOOP, it is titled,
"Invitation to CLOS", where I invite everyone to join the party,
not make it the exclusive club with secret parenthesized handshakes,
which has been its history.
I'll make this concrete:
I propose a new dialect which has a simplified syntax, that makes it accessible,
but without losing it's power, by adding a few simple keywords
to replace parenthesis. It isn't (foo 1 2) vs foo(1,2) that's the barrier
or problem, it is having this:
(let ((x 10) (y 20))
(do ((i 0 (+ i 1)))
((> i 10) x)
(cond ((> x y) 10)
((< x 0) 20))))
When it is much clearer and accessible if it is written like this:
(let x = 10
y = 20
do
(loop for i from 1 to 10
do
(if (> x y)
then
10
elseif (< x 0)
then
20
else
nil)
And has no less power than the more parenthesized version:
The functional view is just the same, and macros are no less powerful.

Having used both languages pretty extensively, both in and out of academia,
I don't think this is a fair assessment at all.
First of all, the claims you make about Perl-over-Prolog have been made
extensively about C-over-Perl (and even VisualBASIC-over-Perl): namely,
that C/VB is for the "real world", and Perl is a "toy for hackers".
I think many of us in c.l.p.* know where we stand on this. :-)
Second: Prolog is an excellent languange for implementing expert-systems, and
there are many expert-systems applications out there which you might
not be aware of. The most common seem to be "diagnostic assistant" tools...
I've heard of the operational use of:
* a medical diagnosis application, intended as a teaching tool I think.
* a system for assisting physicians in the prescribing of
several drugs to a patient w.r.t. avoiding dangerous interactions
and allergic reactions, and also usable by pharmacists.
* a system which assists chemists in the reading of spectroscopic
analyses to determine the composition and structure of an unknown
molecule.
Nowadays, with people embedding language-interpreter code in their C applications,
you can't just look at a system running on a PC and say "that doesn't use Prolog
or CLIPS or Perl or XXX". You might be surprised at what's really going on
behind the scenes.
There is little wisdom in arguing the virtues of a screwdriver over
a hammer. The right tool for the right job.

That message is really coming from your shell, telling you why the

if..elsif... constructs will check every *condition* until *one*

I'm unaware of).
Perl doesn't have a switch() statement, but there's nothing you
can't do by way of switching, testing, conditionally executing,
falling, breaking....
My Camel is at home (I took the car this morning :-), but I believe
there's some discussion of this in there.

Give us a f*cking working flock() for solaris and we'll stop
using file existance.
besides, under solaris open.2 manpage:
O_EXCL If O_EXCL and O_CREAT are set, open() will
fail if the file exists. The check for the
existence of the file and the creation of the
file if it does not exist is atomic with
respect to other processes executing open()
naming the same filename in the same directory
with O_EXCL and O_CREAT set.
it works. it works by design, it's guaranteed to work.
(on solaris anyway, where flock() is unavailable.)
Thanks for the opportunity to vent,

Subject: Troubles with IIS and ODBC
Message-Id: <5jljm1$ne$1@morgoth.sfu.ca>
Hello,
We've recently reinstalled NT 4.0 on our web server, and have run into some
difficulties. We're using Perl 5.001, Build 110, along with ODBC.pm. This
has worked flawlessly in the past, but something happened during the
reinstall. Here's our error message:
HTTP/1.0 200 OK
Server: Microsoft-IIS/2.0
Date: Tue, 22 Apr 1997 21:38:48 GMT
Content-Type: application/octet-stream
Can't load 'C:\Perl5\lib/auto/Win32/ODBC/ODBC.pll' for module Win32::ODBC:
5 at
C:\Perl5\lib/DynaLoader.pm line 450.
at C:\Perl5\lib/Win32/ODBC.pm line 887
BEGIN failed--compilation aborted at C:\Perl5\lib/KA/Administrator.pm line
67.
Connection closed by foreign host.
Now then. ODBC.pll is located in that directory, we're running ODBC
version 3.0, and the program runs fine from the command line. Permissions
are full control for the ODBC.pll file.
I've written a one-line program that fails as well:
use Win32::ODBC;
That's all it takes to produce the error message.
Note that it runs fine from the command line, but not at all from the web
server.
I've printed out @INC, and %ENV from both the web and the command line -
both @INCs are identical, and while %ENV were different, I didn't see
anything important missing.
We're really at a loss here, and our server is down until this is fixed, so
any ideas would be much appreciated.
Thanks,
Darren

Does anyone use WatCom?
I too use Borland, if Watcom has a nice interface, Id use that.. now if
someone would comeout with a complier with a tabbed window editor (and a
great compiler), that would be great (instead of this cascading windows
crap)

$vi is a *reference* to an array, not an actual array,
so $vi[0] doesn't make sense. What you want to say
is $vi->[0] or $$vi[0].
You need to go re-read Camel chapter 4 and/or man
perlref again. This notation is clearly explained in
both those references.

Interesting. I should inform about this three different copies of
Perl/Tk (XFree86, Open32 and PM) which sit on the disk of my OS/2
