carriage returns in HERE statements

[bdz]

I am running Ubuntu GNU/Linux Edgie.

I have a program that is using a here statement to print a message in
a terminal window.

sub info {
print << "HERE"
\~\~\~\~\~\~\~\~\~\~\~\~\n
Line 1 \n
Line 2 \n
Line 3\n Line 4\nLine 5 \n

\~\~\~\~\~\~\~\~\~\~\~\~\n
HERE
}

The message is printed out in this fashion

~~~~~~~~~~~~

Line 1

Line 2

Line 3
Line 4
Line5

~~~~~~~~~~~~

That is the carriage returns not marked by \n in the script are
printing to the
terminal as carriage returns giving me double spaced lines unless I
group all the lines on one line (as in 3,4,and 5.

I did not have this problem when I was using HERE statements under my
previous (obscure non-windows) operating system. Can anyone illuminate
this matter?

You typed the program output (and made three typoos in the process) -
please don't do that. cut-and-paste instead.

Your program is apparently producing the correct output (we don't know
for sure, since you typed the output instead of cut-and-paste). When
you use a heredoc, every single character is included (including any
newlines that you put in the text by way of hitting your ENTER key).
If you terminate a line with a \n you get two newlines - one that you
included by hitting ENTER and one that you included by typing \n.

If you saw different behavior from another program it's probably
because $\ had been redefined.

Thanks for the explanation. I am sorry I typed it, i was trying to
simplify. However knowing that the newlines that are in the text will
print to the terminal without having to put in a \n solves my problem.
Amigas do not respond that way when here documents are used in a
terminal but I am aiming for cross OS capability.

Thanks for your useful comments on my typing. I see the three
"typoos", forgetting the ; after "HERE" and Line5 instead of Line 5
in the output and the code should have produced two blanks before the
final set of tildes.
