Hi,

I'm doing this assignment for a perl cgi course and it called upon me to use the <<XXX string terminator. It's discussed on p. 66 of Programming Perl, 3rd edition.

I am wondering how to use it in a subroutine rather than the main portion of a program.

If I do this:
print <<GOOFY;
    <html>
    <head>
    <title>
    Chats
    </title>

    <script>

    function callrefresh(){
        time=15;
        millisec = parseInt(time*1000);
        setTimeout('refresh()',millisec);
    }

    function refresh(){
        this.location.href = "refresh.pl";
    }

    </script>


    </head>
    <body bgcolor=dcdcdc onload=callrefresh();>
    GOOFY

I am fine.

However, if I do this:
sub chatOutput
{
    print <<GOOFY;
    <html>
    <head>
    <title>
    Chats
    </title>

    <script>

    function callrefresh(){
        time=15;
        millisec = parseInt(time*1000);
        setTimeout('refresh()',millisec);
    }

    function refresh(){
        this.location.href = "refresh.pl";
    }

    </script>


    </head>
    <body bgcolor=dcdcdc onload=callrefresh();>
    GOOFY
}

I get an error:
Can't find string terminator "GOOFY" anywhere before EOF at <filename> line (the line that contains <<GOOFY)
How does one enable use of <<GOOFY within a subroutine?

Thanks in advance!

Tony
