    what is wrong with this: I am running perl 5.8.1. 
     open (RF,"<:raw:scalar", $$record{data}) or die "Couldn't open memory
+ file: $!";
  
        while(my $line = <RF>){

print "\n in while \n";
        }

close(RF);

    It doesn't die. (i verified there is data in the variable) and it never prints "in while" so it appears <> is finding no lines. any ideas thanks again

    Thanks! Its cool you can read from memory like filehandle (learn something enw everyday!!!) Once i get it to work i will be thrilled!!

      You might try changing the :raw to :crlf. Try also setting $/ to \n.

      open my $fh, "<:crlf:scalar", $record{'data'}
    or die ...;
{
    local $/ = "\n";
    while ( my $line = <$fh> ) {
        print "in line\n";
    }
}
