Re^2: Need help with a simple perl script

Actually, no. Why should anyone set $_ to anything just to overwrite the value in a for loop? The code works - why does it need any modification? See perlvar for the special variable $".

Okay, I agree with $". Thanks For the while loop, as "print" is not contained in while, it ll take the inputs all the time without printing anything.	[reply]
