I just ran into this the other day. It is easy to forget the different
ways that the << operator can be used. Basically Perl looks at the way
you quote your termination string (HERE, EOF, etc.). If you don't quote
it, Perl will assume double-quotes. Put single quotes around your
termination string to avoid accidental interpolation in your
strings(E.g. <<'HERE' instead of <<HERE).
>From perldoc perlop:
print <<EOF;
The price is $Price.
EOF
print << "EOF"; # same as above
The price is $Price.
EOF
print << `EOC`; # execute commands
echo hi there
echo lo there
EOC
print <<"foo", <<"bar"; # you can stack them
I said foo.
foo
I said bar.
bar

Subject: The "@" symbol
trying to include the following code with the abc.pl script...
the snippet works in an html/css environment
print <<EOF;
<style type="text/css" media="all">
@import url("theta.css");
@media print {
body {background: white; color: black; font: 12pt Times,
serif;}
#noprnt {display: none !important;}
}
</style>
EOF
The "@" symbols are misread and thus this cause errors... escaping the
"@" symbols doesn't work
