Why doesn't my "wallpaper" show?

I have a wallpaper background I would like my CGI program (on a UNIX server) to use when it returns a page to the user. Here is an example:

#part of a cgi program
sub error {

      print<<EOF;
Content-type: text/html

<HTML>
<HEAD>
<TITLE>Error</TITLE>
</HEAD>
<BODY BACKGROUND="bground.gif">
<P>Name and address fields must be filled in for this form to be submitted successfully
</BODY>
</HTML>
EOF
}

When I do this, I get the annoying "Document contains no data". However, if I omit BACKGROUND=bground.gif, the program works, and I get the defalut grey background. I have 2 copies of bground.gif - one in my public_html directory and the other in my cgi-bin. What am I doing wrong?

Hard to say. The only way that the browser will report "No data" is if

1) The line Content-type: text/html\n\n was sent.
2) And nothing else.

Nothing in your code is inherently wrong, although I would recommend a few things:

1) Move the content-type outside the print error section:
2) Use something besides "EOF", and put it in quotes:

sub error {
print "Content-type: text/html\n\n";
print<<"ENDOFERROR";
<HTML>
etc....
ENDOFERROR
}

Other than that, I would look for typos. There is no reason for whatever is in the BODY quotes to affect the output so drastically as you describe.

Finally, make sure you are buffering your output by adding a
$|++;
or even a
$|=1;
at the top of your program.
