That's about the last thing I would do.
Why not use a DBM file? Or, if you plan to read/write the entire hash
at once, something like Data::Dumper, Storable, or FreezeThaw?

!! foreach (sort keys %hash) {

What if either the key or the value has either a newline, or a tab in it?
Then it would fail, wouldn't it?

I was sitting there thinking thats not right, thats not right, thats not
right - but disturbed as I was by the spectacle of the Morris Dancers
doing the peculiar "Baby wipe dance", disturbed as I was by the lovely
Ook! (please do see the Hall of Flame at <http://www.gellyfish.com/flames>)
I make my recompense:
On London fell a clearer light;
Caressing pencils of the sun
Defined the distances, the white
Houses transfigured one by one,
The 'long unlovely street' impearled,
O what a sky has walked the world!
(I asked Mrs G to bring some poesy from upstairs and thats what she brought).

If your definition of 'works great' means "has really dreadful

Yup. Separators.

Don't forget to check for CPAN modules, too. I've heard tell

I said I wasn't thinking about Tom C's posts. That didn't imply that I

Is there a way to nicely trap those errors and

You don't give us much to work with, do you? Supply a code snippet
that produces that warning and maybe someone can help you out.
Btw, line 78 is where the routine for absolute value is defined.

I have a subroutine that should search through a file and replace a line
on the given parameters i give it. So, if in the file (/some/file)i
have:
foo bar
tomorrow sucks
yesterday rules
and pass it the parameters:
&replace("tomorrow sucks", "always will", "/some/file");
I keep getting the new file with only:
"always will", everything else has been wiped out. Any suggestions?
The code for &replace is below:
sub replace
{
my($old_line,$new_line,$file) = @_;
my($rep) = 0;
system("chmod +w $file");
open(OUT,">$file.bak") || die "Can't open $file!";
open(FILE,"$file") || die "Can't open $file!";
while(<FILE>)
{
if (/$old_line/)
{
if ($_ eq "$new_line\n")
{
print OUT;
$rep = -1;
}
else
{
print OUT "$new_line\n";
$rep = 1;
}
next;
}
print OUT;
}
close(FILE);
close(OUT);
system("/bin/mv $file.bak $file");

]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.
