No $line contains a line from a file whose name is in @ARGV or from
STDIN. You wanted
$line = IN

No ... :-)
The while(IN) reads a line into $_. So, just chomp;
I think Jenda's original post of $line = IN was meant to be like this:
open (IN, a.txt) ;
while ($line = IN) {
# $line contains line from a.txt
}
Why not just do chomp; ? Since we are using $_, it will work on it without
any var...
open (IN, a.txt) ;
while (IN) {
chomp;
# $line

No
I am using a while loop to read a file like
open (IN, a.txt ) )
while(IN)
{
---
---
}
This will read the entire file reading line by line.Now the problem is that
inside the while loop at some particular place i want to read just one
line(next line) without going back to main loop.I am trying
open (IN, a.txt) ;
while (IN) {
chomp ($line = );
# $line contains line from a.txt
}

Ok, try this:
open (IN, a.txt);

Yes, grep has some great benefits if used properly! Unfortunately a lot of
people, myself included up until a couple of months ago, either don't know
about or how to use it. I didn't figure I would throw it out there since
there was already some confusion :-)
