Hey Gr8 ppl,

        I have written a piece of code to print the file contents. Here is the code,

#!/usr/bin/perl -w
use strict;

open FILEHANDLE , "$filename" or die "cannot open the file : $filename
+ :$!";
my @array = <FILEHANDLE>;

foreach ( @array )
{
   chomp $_; #This Chomp plays an important role here;
   sleep 1;
   print "$_"; #But this line does some thing strange.

}

close FILEHANDLE ;

[download]

In the above code, If i comment the

chomp $_;

    The sleep function executes first then it prints the contents of the file. But where as if I uncomment the line, (i.e) i didn't remove the new line char at the end of the file contents, it is doing good. Can you ppl able to guess why it does so ? Nowhere they have mentioned about sleep's this behavious. What may be the relation ship with the sleep and the newline entry ?



Thanks in advance.
