It is not just about lines. There can be huge and subtle differences
between the storage, transport and usage formats of data. The Internet
Message Format header for instance, in which a header field can be
folded into several header lines (continuation lines start with
whitespace). Or the NNTP transport format, in which the dots at the
start of a line are temporarily doubled. With both, CRLF is used as line
ending, mainly to enable presentation (of even the transport format) on
the simplest 80x24 terminals without special software.
Already mentioned are the systems that work with fixed size records.
These records often have several positions at the start that contain
metadata.

Let me add the fact that BBEdit, which I use (don't know about the free
BBEDit Lite), allows the user to pick the line-ending default among
Macintosh (0x0d), Unix (0x0a), and DOS (0x0d0x0a) (see the "Text Files:
Saving" menu under Preferences) and that page 163 of my copy of the
Camel Book, 3rd Edition, shows:
Escape | Meaning
--------+------------------------
\n | Newline (NL, CR on Mac)
\r | Return (CR, NL on Mac)
perpetuating the old Mac OS 9 line ending style.

Hi
I get message 'Child record found' when deleting parents in Oracle.
How can I from perl dbi instruct Oracle to delete also child when I
delete parents?
Thanks

The same way you would do it were you not using Perl.

You'd handle it just like you'd handle other error conditions, by using
eval.
Take a look at the documentation for eval (perldoc -f eval) and for DBI
as to how to handle error conditions. Show your code if you're unable to
get this to work.
Straight out of the documentation for DBI:
eval {
...
$sth->execute();
...
};
if ($@) {
# $sth->err and $DBI::err will be true if error was from DBI
warn $@; # print the error
... # do whatever you need to deal with the error
}
You could check $@ to see if it contains 'Child record found'.

Oh no, now we have "CPAN" and Bin Laden's name in one posting. The NSA's =
computers will trigger and the exact location of CPAN will then be=20
auto-fed into some missile's computer.
But then ... maybe the computer is programmed in Perl and it blankly=20
refuses to incinerate CPAN?!?

You need to use single quotes, or they will be interpolated away.
com => q/c:\texmf\miktex\bin\latex.exe test/,
Also think about:
com => q/"c:\tex mf\mik tex\bin\latex.exe" test/,
(if you need to keep the "" because a space is embedded)
