Use:
RaiseError = 0
instead so that your script will not raise an exception and die. Then
check $dbh-err.

How do you see I try to print the next line after the REGEX match, but I
obtain the next result:

Name:\t;

This won't work because $' does not contain the next line - it only contains
the rest of the line after the match. If you want to print the next line, you
can either do:
my $next_line = $html_fh;
chomp($next_line);
print $next_line

Define next.
You can use POSIX::ceil(),
but then -1.23 becomes -1 and you might want -2 there?

Two things I'm unsure of:
1) is the `: $!' meaningfull here?
2) do I need a `next;' following to make `File::Find' go

The while loop is while (FILE) on the most recent found file. I
want this `next LABEL' to bring on a new file... not a new line in
while loop.

If so, how do I let the `next' know that open has failed?
That is, how do I test exit status of open function?
open() returns true on success and undef (false) when it fails.
Is it just as
in shell programing ($?)?
No.
ok, then how is it done

HTH,
Definitely and thanks for the examples. I think I was making this
more complicated that it needed to be. It's slowly sinking in what
all a `return' can do.

if you don't mind dieing, or I often prefer using 'unless' then I
don't need to worry about a dangling else, so similar to what you have
above,
In this case I do.
unless (open(FILE, $file)) {
warn Failed open: $!;
return;
}
Ah

Hi Harry,

I'm getting this output on stderr from a next clause:

sub routine. That is why I put it there. So how

Use 'return' to exit from a subroutine. Use 'next', 'redo', 'last',
and 'goto' to alter the execution path in loop constructs; they must
appear /inside/ the block owned by the loop construct or within a
sub-block.
Ahh, ok thanks. Return turns out

# I added this statement. I don't understand the /'s in the statement
address.
So, your line:
next if /NAS-IP-Address = 192.168.0.1/;
change to
next if /NAS-IP-Address = 192.168.0.1/;
and it will skip to the next line if that line ever comes up.

A 'next if /./' is a short form
