Well. Sure if the code realy looked like that.
I expected in the actual code there will be something between the
while() and chomp($line = <>). :
while (<>) {
... some code
if (we_need_next_line) {
chomp($line = <IN>);
... some more code
The problem I was trying to highlight is that in the while() the
original poster reads from IN, while in the other statement he reads
from a file in @ARGV or STDIN.
The code proposed was :
while (<IN>) {
chomp ($line = <>);
Do you see? He is reading from the same filehandle.
I think he wanted to write
while (<IN>) {
chomp ($line = <IN>);
BTW, if there was no code before these two lines he would get every
other line in $_ and the other lines in $line. So he could process
the whole file this way, if he was carefull.
