Hi

out the out. how
$i = 0;
while()
{
$i++;
if ($i > 10)
{
last;
}
$var = $_;
$msg2="$var\n";

Re: How to empty the buffer
If you are using 'strict', you must applies '$msg2 = $var' as 'my $msg2 =
$var',
You are highly recomment to use strict, because you won't need to take care
of
this question at all, $msg2 will destroy after the sub/loop, the entire
scope ends
anyway.
For your question :
undef $msg2 ;
or
$msg2 = undef;

You have coded an algorithm which prints the tenth line in
a file. The loop just discards the next 9 lines. Then you print
out the tenth line. Since you referred to a buffer, I doubt that
is what you were trying to accomplish.
# Discard next 9 lines
foreach 1 .. 9;
print scalar , "\n";
