Hi Monks, again, seems like simple problem but I can't solve this. I would like to control one program (that is normally controlled from terminal) with perl program. So , I understand there are few ways of managing it. I started with reading output of the program using pipes and I can not do it. Here is an example of what I am talking about: 
#
open my $READ, "-|",  "./dialog.pl";
while (<$READ>)
        {
                print $_;
        }
close $READ;

Here is the dialog.pl program that I am trying to interact with: 
print "How old are you? ";
my $age = <>;
print "You are $age.";

[download]
The way I understand first program will open dialog.pl program and display "How old are you?" in the terminal,but it is not the case. What is the issue here? I would like to catch output from dialog.pl , and respond to it. I also understand that I will have to fork the program to be able to do writing and reading from dialog.pl at the same time. Thanks like always. Robert
