You shouldn't have needed to do that. I presume this is a Unix machine;
did you compile Perl from source? If so, you should have been given the
opportunity to specify its library paths.
There are ways to work around this, but you don't really want to. What
you want to do is get the right paths compiled into Perl itself so that
you don't have to worry about it.

Wow! Now *that's* a recommendation! Just don't try discussing them with him
in per(l)son... he has this weird smile he gives you... very
unnerving. :-)
Remember - Elijah's code frightens Randal.
I try to look at it only a few characters at a time, myself. :-o
ObOnTopic: MRE *is* pretty darn good. Granted there are errors in the
first edition (although many, if not all, have been corrected in later
printings), but the errata is easily available online - just carry it
around with you while reading. Very little is serious, just little
typoes here and there... of course w/REs, that *can* be serious...
Still it reads well and is almost unbearably informative. Friedel
knows his stuff.
Not to knock Advanced Perl Programming, but given the imortance of REs
in Perl and the fact that Friedel really goes into them from most
directions, not just from Perl, would give MRE the nod in my opinion.
Ideally, of course, you should just get both. Work towards that
bookshelf (local reference)

Two words:

You really ought to check before you post.

PS. I have used both. I have the pages as HTML on a web server here
somewhere. I can even access them directly from disk. I never use
them. They're there for other people who occasionally use perl. I use
perldoc all the time. I would use man if Solaris didn't have such a
broken version of makewhatis installed. Typing man -F is more work to
me than typing perldoc. Anyone I know who ises perl a lot, doesn't
read HTML pages. You cannot grep HTML pages reliably. You cannot
search them quickly.

Note that if your newsreader generates message IDs for you (rather than
letting inews or the news server do it), there are even better ways than
adding individual score file entries for each of your message IDs (which
is what trn always used to do).
I have the following entry in my global SCORE file for use with Gnus:
("references"
("<m3[0-9a-z]+.fsf\\(_-_\\)?@windlord\\.Stanford\\.EDU>" 200 nil r))
which will match all references generated by Gnus for my posts. Believe
me, doing this makes Usenet *infinitely* easier to follow.

If you want to read the entire file into memory, it is pretty
easy. The $/ variable controls the "input record separator" which is
the characters that each record read with the <FILEHANDLE> or
FILEHANDLE->readline() functions consider the separator between
"lines" of input. So reading an entire file into a scalar will
probably be something like this:
{
local $/;
$scalar = <FILEHANDLE>;
}
and then the entire contents of the file is in $scalar.
Of course, an array is a "variable" too, and the readline operator
returns all the remaining lines when given a list context. So getting
each line in a successive element of an array would be something like:
@lines = <FILEHANDLE>
See the section on I/O operators in the perlop man page for details:
<URL:http://www.perl.com/CPAN/doc/manual/html/pod/perlop.html#I_O_Operators>
But one last question, do you really need the entire file before you
can make any changes? If you can just read a portion of the file at a
time and process that portion, you might be better of using the line
at a time processing that uses many of perl's common idioms.

[courtesy cc of this posting sent to cited author via email]
After sleeping, somewhat, on the problem - I would say
I agree with Tom Christiansen - my logic is lacking. So, I
wrote a small perl script which olnly calls subroutines via
the method cited in perlref/perlsub and I cannot get
them to work under 'use strict'. Use diagnostics complains
about many things regard this subject - but primarily it
keeps saying -
Can't use string ("CODE(0x257d28)") as a subroutine ref while "strict refs"
in
use at Filebase_Tabs.pl line 207, <prjCF> chunk 1 (#1)
(F) Only hard references are allowed by "strict refs". Symbolic
references
are disallowed. See perlref.
Uncaught exception from user code:
Can't use string ("CODE(0x257d28)") as a subroutine ref while "strict
r.
main::readCF() called at Filebase_Tabs.pl line 108
So, off to the drawing board again :-)
All I really wanted was a 'case-switch' routine to allow the data input
stream
to drive the Perl script -
[Switch]
data:Tranalstion:Other Stuff here:etc
data:Tranalstion:Other Stuff here:etc
data:Tranalstion:Other Stuff here:etc
[SwitchII]
...
Thing is, I won't know how big each section is...
Could anyone point me in the right direction?
Thanks for the input to all who responded to my previous
rantings, I appreciate your insight and efforts :-)

Wow, your newservice must be mucho behind :P
I have this part of the program working now, thanks to Russ Allbery
and .. hrm... Chipmunk : P
Although I much prefered Russ's suggestion, for clarity I decided to
go with what Chipmunk (Mr. Chipmunk? heh) suggested and do the
separate array/hash thing.
The reason for this was that I thought I would be easier for someone
else to understand and modify the way he had it outlined and it would
also be easier to add day-of-the-week names.
Anyhow, my thanks to the two of you and to anyone else I might have
missed that posted a suggestion.
I really appreciate it.

You definitely want to read section 5 of the perl FAQ:
perldoc perlfaq5
(specifically the question starting with "How do I change one line in
a file")
You will also want to read the documentation on open, close and the <>
operation
perldoc -f open
perldoc -f close
perldoc perlop
(see the section on I/O operators)
If you read those parts of the documentation that comes with perl, you
will know the answer.

You could of course use perl's builtin rename() as long as you don't
move the file over file system boundaries.
perldoc -f rename

Bob:
You should be asking on a CGI newsgroup, then. But, to save you (and
them) the trouble, go to http://www.altavista.digital.com and run a
search for "Matt's Script Archive" (with the quotemarks), or the words
guestbook and script (put a plus sign in front of both words to pull up
pages which MUST include both words).
In the future, too, look at the name of the newsgroup to which you are
posting. This one is "comp.lang.perl.misc" - do you see anything
in the newsgroup name about guestbooks or CGIs? Nope. A more appropriate
newsgroup would be comp.infosystems.www.authoring.cgi, which covers
CGI scripting, specifically.

why dont you use print LOCATION with the arguements and leave sockets
alone, maybe i am misunderstanding what you are trying to do.
if your script has done what it has to do and now needs to take data
to another script you can use print Location the same as print FILE.

Almost. I would have suggested "Tip of the day" vs "FAQ".
In fact, given Tom's much-needed crusade against newbies
posting questions without doing their homework, perhaps we
need to package the FAQ as a "Tip of the day" help file!
Perhaps a tip could be popped-up every time a newbie
started their newsreader? Of course, we'd probably need to
be unethical and exploit some security hole to make the
tip pop up, but that shouldn't be hard, right? :-) :-) :-)
(In other words, I'm kidding.)

Perl/TK! I believe there are all sorts of GUI programs using just
Perl and TK. I dont know more, but I dont know why this would be
groundbreaking.
A friend of mine loaded a Win95 port of Perl that came with all
kinds of GUI stuff as examples (using TK). And that's Win95!

Sorry, but if you hand out incorrect advise, you share in the blame.
Had you told people that they risked ignoring articles with legitimate
return addresses but that you were willing to take the risk, I would
have considered that legitimate. Misinforming people about the
consequences of following your advise is illegitimate.

rec.arts.comics.creative was converted from unmoderated to moderated.
Three months later, the problems were almost gone; after a year, there's
nary a difficulty in sight. It takes a while, but it happens. You just
have to encourage your users to bug their local ISPs to change the group
status.
Larger groups, of course, will have more problems.
(This is not to say I favor moderating in place. For this group, I think
creating a new moderated group would be a better approach.)

Message-Id: <null>
Administrivia:
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.
