Message-Id: <7c2sg4$1jp4$1@news.uk.ibm.com>
Hi,
&ReadParse function from cgi-lib.pl fails returning variables. Seems it
stops elsewhere in the function. &PrintHeader works fine. I think its the
funktion in cunjunction with the active state perl port...the cgi module
works fine.
I want to develop on my WIN95 then transfer the perl script to our unix
server, so I cant using the module.
Any ideas

Hi.
I am going to solve some mathmatical problems with perl.
There are some perl modules on numerical analysis but I could not find
out the Gamma and Bessel functions.
Do you have any information about these ?

Create your script as usual, then run pl2bat on it to create a BAT

Do you mean it hangs, or it stops? If it stops, there's a simple
solution: eval {}.
Call the whole processing of ONE file in an eval BLOCK. If the code
fails, eval exits with $@ containing the error text. You can continue
with the next file anyway.
while(defined($file = shift)) {
eval { &process($file) };
&log("Error for $file: $@} if $@;
}

Where can I get perl-mode for emacs?
Since Emacs version 19 patchlevel 22 or so, there have been both
a perl-mode.el and support for the perl debugger built in. These
should come with the standard Emacs 19 distribution.
In the perl source directory, you'll find a directory called
"emacs", which contains a cperl-mode that color-codes keywords,
provides context-sensitive help, and other nifty things.
Note that the perl-mode of emacs will have fits with `"main'foo"'
(single quote), and mess up the indentation and hilighting. You
are probably using `"main::foo"' in new Perl code anyway, so this
shouldn't be an issue.

That's the whole point. lc() is slow for very large strings. (n log n)
is big for large n. So for small sets and small strings, expect faster
execution for the simple approach, because of the lack of overhead.

"\n" is always the last character in each string. Of course it won't
work.
If $_ was the WHOLE file (set $/ to undef), I'd expect it to work.
But what you really want is probably something like:

Actually, I think you should also include the line where the $SENDMAIL
variable is initialized. Presumably you're opening a pipe to the
sendmail program, though I don't see it in the open statement. It might
be in the $SENDMAIL variable, though that would strike me as a kind of
odd way to do it.

as I mentioned in my post, perl is one of the languages saddled with

I never said AD1-9999 are the overwhelming majority of dates.

for the overwhelming majority of cases ANYONE has to consider, I believe
4 digit AD dates are the solution.
obviously, that's not enough for Biblical scholars. nor for people
predicting the heat death of Sol. nor for ... well, there's got to
be OTHER people for whom it's not enough.
but in the overwhelming majority of the cases under consideration, even
including these people, it is enough.

there has been for a long time. when did you first hear about a 106
year old person getting a mailed notice reminding him/her that school
was starting, and he/she'd better be ready to attend?

it a tangential argument, but it's far from silly.

if they're in ISO yyyymmdd format, they do.

yes; but storing them as 2 digit dates is the crux of the problem. not
inputting them (with an implied window) or printing them.

I leave that to my wife; I'm far too likely to forget. :-)
(actually, :-( would probably be more appropriate...)

Well, after 6 months, here's the answer to the quiz: what do we do about
comp.lang.perl.moderated. Answer: nothing.
]From: Russ Allbery <rra@stanford.edu>
]Date: 21 Sep 1998 19:53:43 -0700
]Subject: comp.lang.perl.moderated available via e-mail
]
]It is possible to subscribe to comp.lang.perl.moderated as a mailing list.
]To do so, send mail to majordomo@eyrie.org with "subscribe clpm" in the
]body. Majordomo will then send you instructions on how to confirm your
]subscription. This is provided as a general service for those people who
]cannot receive the newsgroup for whatever reason or who just prefer to
]receive messages via e-mail.
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". Due to their sizes, neither the Meta-FAQ nor the FAQ
are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
