Dear Monks

I have this external program that when started requires some input. For example, I could do something like
#! /usr/bin/perl

open OUT,"| ./progX" or die ;
print OUT "X\n\n1\n2\n\n\n" ;
close OUT ;

This works just fine.
However, before progX terminates it writes some useful information to STDOUT. Normally I would do something like
open OUT,"| ./progX > output" or die ;

[download]
 Than I would open the 'output' file and read the content.
This works great (as long as I have write permissions so I can create the output file).
For some reason this approach doesn't feel right. So is there a better way to catch the output directly in my perl program ?

ThnX
