Well, if there is no equal sign, then split won't be able to provide a
way to stop this (you were talking about the third argument to split,
right?)

I do wish it were this simple. But regardless of whether I HAVE to
excape the period, escaping the period does not do harm as this works
with other variables which are also followed by the escaped period.
Therefore, the escaped period is not the source of the problem.
It also is not a problem with the directory structure or file locations
because, again, this works with other variables. I have also tested to
see whether the variable is merely a reference by dereferencing it, but
that does not work.
As far as the value of the variable, I have tested that too by a
print "$old_date_fields[0]";
statement which, indeed produces that value that I expect (and which I
have tested by actually using inplace of the variable as well as
directly assigning to a different variable that I used in its place).
The following peculiar phenomenon might shed a clue:
The program also freezes if I merely assign the value of this variable
to another variable.
By way of background, this varible is obtained by reading in a line from
a file, then spliting this line and assigning the parts to an array, of
which $old_date_fields[0] is the first element. For some reason, the
nature of how this variable is obtained seems to choke the
program????!!!???

When you're printing out the contents of a variable to see if it really
contains what it's supposed to, it's always a good idea to surround it
with highly visible delimiters like angle brackets or square brackets;
otherwise it's easy to miss things like whitespace that shouldn't be
there (which is the source of a surprising number of bugs).

That usually indicates that the different ways of obtaining the variable
are really obtaining different values, even though on first glance they
look like they shouldn't. Try showing us the actual code that you just
described; be sure to copy and paste it rather than retyping it (retyping
it can introduce typos that give false alarms or worse, can "correct" the
actual error and thus hide it).

Maybe I wasn't clear enough:
You do not think, but have you actually checked? Did you include the
$! variable in the error message? Do you check for errors at all?
Where is the _actual_ _relevant_ piece of code that shows us that you
did all of the above. And when you did, what was the error message?

A more conventional way in perl to do this is:
# perl -w
@a = qw(a b c);
my $foo = "./banana/${a[0]}.foo";
print "$foo\n";
__END__
./banana/a.foo
The curlies are the part of the perl syntax that were designed for
this. BAckwhacking things is a bit misleading.

This leads me to think that maybe:

Does the variable maybe contain a newline? Did you chomp off the
newline when you read it from a file?

The _only_, repeat _only_, way to check the validity of an email
address is by sending an email to it, and seeing if it bounces. And
even then, you will need to inspect the actual content of the message
to find out why it bounced. And even then, the actual content of the
message may not describe the real reason for a bouncing email. And if
the email doesn't bounce, you still don't know anything with
certainty. All you know is that there is an MTA somewhere that either
accepts or silently drops email for that address.
When you get an email back, that is clearly written by a human, and
not an automaton, then you can be fairly certain that the email
address was valid.
Read perlfaq9

How do I check a valid mail address?

Implement the script as a singleton.
It's hard to tell exactly what your problem is. We don't know what the
code of the program is. We don't know what the error messages of the
program are. Only you know. Check the error logs of your web server.
Rewrite your script so that it doesn't bomb like that, but instead
writes some information to stdout. Check if maybe your script writes
to a file. If so, you might be able to do something with file locking.
I could go on guessing for hours what might be wrong. But I won't

Yes. I do this all the time. If you are really clever you can create a
package of your perl and just install perl onto the target machines via the
pkgadd command.

About as much as a dog needs a fish on its back.
>3) Is it possible to install new perl modules without C compiler?
I would advise that you build your perl in a defined directory structure on a
development machine, build a package for pkgadd from there. See above.
>4) Are there any other solutions for this job?
Typically the way I skin this cat is on my development box "schooner" I build
perl and install all of the optional modules into a tree "/opt/gnu." I also
put any other tools that I'm going to be installing on my production machines
in there as well. I then use pkgmk to create a package for pkgadd. I use that
package to install perl and other tools onto my production systems.
To keep the perl directories up to date, I have another machine that always has
the latest stable version of any Open Source and or GNU tools installed on it
and I use rsync to keep the other productions systems up to date.

Subject: POP is pooped!
Message-Id: <37C2159A.21AC@mendonet.com>
I can't seem to get my pop to pop!
The info contained in the docs isn't getting me there; very scant:
It has:
pop - remove the last element from an array and return it
and
$tmp = $ARRAY[$#ARRAY--];
I want to "pop" off the last line if a logfile array @accesses and
assign it
to variable $accesslast . Is the last element in the array is not a
line?
The logfile entries are written with an ending newline and look fine.
open(KEYS,"$keys") || die print "Cannot Open Keys Data: $!\n";
flock(KEYS, 2);
@accesses=(KEYS);
close(KEYS);
$accesslast=pop(@accesses);
chomp($accesslast); #whack off the newline
{
($item1,$item2,$item3,$item4)=split(/ - /,$accesslast);
other stuff
}
The loglines are written with `` - " delimiter (space hyphen space)
hence the / - / split
Any suggestions will ge greatly appreciated. TIA Jon

use CGI qw(:standard);

This works from Apache as script.cgi?var=value.

Well, depending on your shell, maybe you can. Your question has
nothing to do at with perl, but is a function solely of the shell you
use to start the perl program. Look in the documentation of your shell
to find out how to do that.
Alternatively, maybe you should consider getting this sort of input
from a file, or stdin, or something like that. Saves a lot of nasty
shell escaping and quoting.

Rusty,
I'm a bit confused by what you are trying to do. I'm guessing here but it
looks like your trying to call a sub by the name of fetchParameter passing the
literal "MYPARAMETER."
To make this happen you just create a sub, for instance.
---------8< snip example follows 8<-----------
my $thingie = getStuff("key");
printf "%s\n", $thingie;
exit(0); # not necessary, just a habit I picked up.
sub getStuff {
my $key=shift; # get the parameter...
.... do stuff ...
return $whatever; # $whatever should have what I"m looking for.
}
---------8< snip back to the article 8<---------
If you are trying to call your sub as a "library" check out some of the perl
tutorials on creating modules and such.

I bet you he can't. regular expressions cannot parse HTML, except in
some special trivial cases, but never in the general case.
A more correct answer would have been to use the HTML::Parser module
and friends, which is available from CPAN.

I vote for comp.lang.perl.discussions.about.splitting.comp.lang.perl.misc.
Would make it a lot more quiet here.

In terms of how file names and exec differs from UNIX, yes.
I suspect this may have already been fixed, as I can't reproduce it with a
trivial program at home, but it shows up at work. I'll report back when I
get to the bottom of it.

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" from
almanac@ruby.oce.orst.edu. The real FAQ, as it appeared last in the
newsgroup, can be retrieved with the request "send perl-users FAQ" from
almanac@ruby.oce.orst.edu. 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" from
almanac@ruby.oce.orst.edu.
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.
