I'm running Activestate perl 5.6.1. I have a DOS application that resembles a dos shell (call it app.exe). It is my task to write a perl program to operate app.exe. I'm having some grief, though, and am turning to the illustrious monks for help. From what I've read, pipes sound like what I need. I've created a little code to test them out before I get hot and heavy in it. 
open(TEST, "| app.exe");
sleep 3;
print(TEST "the -command");

This is starting app.exe as I see the text app.exe spits out on startup. But it ends up in GetConsoleMode failed error. Any ideas? Many thanks.
