Hi,
I am kind of new at this stuff, but I learn quickly and have one quick
problem I need fixed. Please tell me how I can manage the following problem:
I want to open a file that has data in it and make it into a variable. For
example file X.dat has my data and I want to have the data from that file
become variable $x, so that later I can use $x as a printible object.
Thanks,
Justin Saul

kinda depends on what is stored in the file, but this works fine for me.
# Find user name left by the login script
if(! open(ATHLETE, "< $HOME_DIR/_$ENV{'REMOTE_ADDR'}"))
{
# Could not find file, bummer.
printf("ERROR: Cannot read temporary athlete file");
&EarlyExit;
}
# Otherwise...
$athlete = <ATHLETE>;
chop($athlete);
close(ATHLETE);
i am however no longer using this function 'cause i was storing an email
name coded with the IP address of the client machine. this was needed to
allow more than one user on the system at a time, but prove to be faulty due
to some proxy concerns, which of course has nothing to do with your original
question. just focus on the read and assign.

*pop!* :-)
The main thing you seem to have overlooked is the CGI.pm module. This
module handles the reading of data, the parsing of arguments, and the
conversion of hex escapes. It is strongly recommended that you 'use
CGI' in all your CGI scripts.
A few other things you overlooked...
You should check the return value from your read, to make sure you got
all the bytes you expected.
Instead of $x || $x = 'foo', you can do $x ||= 'foo'. Cute, huh? :-)
When you open a pipe to external command, you also need to check the
return value when you close the pipe. (BTW, you did remember to define
the HTMLdie subroutine somewhere, right?)
The HTML in your script could be improved. In particular, you're
missing the <HEAD></HEAD> section. Other issues: You set a background
color, but neglect to set the text and link colors. Your images need
ALT attributes. You close an </H3> that you never opened.
Despite all that, your script should work well, and it looks like you're
off to a good start with Perl!

Message-Id: <792jd5$gg4$1@nnrp1.dejanews.com>
Hi, I make a file: $outfile = "/tmp/blah.txt"; I then make it unique:
$dateStamp=`date +.%m_%d_%y.%H:%M:%S`; $outfile .= $dateStamp; But when I
test the file with: ( -s "$outfile" ) ? print "size <> 0\n" : print "size =
0\n"; it comes up false when I know it to be true. But when I run the same
script again with out adding the datestamp to the outfile, it comes up true.
For example, the following concat returns true, even though its of the same
form. $outfile .= ".01_31_99.16:48:02"; Could somebody tell me what I'm
doing wrong? Or should I use the perl time functions? Thanks.

In various kinds of Perl documentation I am told that:
?pattern?
works just like
/pattern/
...except that it matches only once between calls to the
reset-operator. It doesn't work that way, at least not for me.
Where can I find info or code examples that shows how to use
??-searching? I have really tried searching the web, but not found any
examples...
Thank you in advance,

OK- I got the program.All I'm trying to do is write the results of a form to a
common file on a shared network drive.
Here's the file I'm trying to append to on the shared drive:
# Output file location
$outfile='\\\\computer\share\myfile.txt';
Here's where I try to write the file
# open text storage file
open (DTXT, ">> $outfile") || exit &errormsg("$outfile $!\n");
print DTXT
"$in{'Zipcode'}$in{'LastName'}$in{'FirstName'}$in{'Address1'}$in{'City'}$in{'State'}
"$in{'WEB'}$in{'DATEENTERED'}$in{'Address2'}$in{'IRANO'}$in{'IRAYES'}\n";
close(DTXT);
It consistantly gives me the error message: "Invalid Argument"
I tried every possible variation of slashes, but I believe that the above is
correct. File permissions are full access for everybody.
Hope this helps. - Gary

No it wasn't.
Questions end with a question mark.
Statements end with a period.
Those are the rules of English grammar.
So that was a statement.
Say what you mean.
Some might say that your poor grammar is an insight
into the quality of your programming.
I'm going to agree with that.

If they used it simply because they were familiar with
it from archaic years, then it would be a problem.
It is a matter of knowing the criteria and trade-offs
and wieghing them between each other.
Pointers and referants are archiac constructs, not
meant for a scripting language IMO.

approved definition of "scription language".
Anyhow, I defined my personal interpretation
of it, and that is what I a working with.

Other languages have OOP without pointers.

Many languages support the idea of by-reference
and by value parameters. You use by-reference
so that a copy does NOT have to be made. (There
are further variations to consider.)

Anyone who has done a lot of programming will understand that sometimes a well

itself is somewhat complex. <<
There are probably other ways to do these that
just simply never occured to you. (I don't

paradigms.)

absurd. <<
Well, I stand behind that claim until proven
otherwise.

Hi,
Why doesn't my perl script run. When I view the file from browser it
displays the contents of the file, instead of displaying the result.
Check: http://www.cs.wpi.edi/~seshu/checkmail.cgi

I am trying to monitor a directory on an Unix machince to look for
incoming files. I can't seem to get the select to work on any files
to tell me if an FTP is open on them or not. Does somebody have an
example script that I can read?

Subject: Using integers in perl
Message-Id: <792q14$jj9$1@dinkel.civ.utwente.nl>
Hi!
I would like to know how I can use a integer from a form. I can add 2 of
those integers, but I can't compare them with another integer(which is
already in the database).
It's meant to make a database for an agenda. I hoped I could put an integer
on each 4th line of the database. This integer should be : year, month and
day sticked together like : 04-10-1998 => 19980410, so you can very easily
sort the list.
Thanks,
Pascal.

Hi, what I meant was is there a sort of PageMill type WSYWYG program
that would allow you to fill in the blanks ie a form creation program
that would write the perl like visual html editors do.

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.
