Aha!: My program requests user input.

If I replaced the <STDIN> with a typical user request, it works fine.

So the problem is getting it to play with STDIN. Now what??

EDIT: Here's a snippet of the code that's not working: 

while(1)
    {
        print "\nEnter the day number you are interested in: ";
        chomp($sol_request=<STDIN>);
    
        #append 0 to the front 
        if($day_request < 100 && $day_request !~/0[0-9][0-9]/)
        {
            $sol_request = "0".$day_request;
        }
        
        if(not -d "/somedir/$day_request/")
        {
            print "\nSol $day_request does not exist! Please try again
+\n";
        }
        else
        {
            last;
        }
    }

When I run the code with the pipe to more, the message "Enter day number" does not appear. Putting in a number works as usual, and the message does not print until after you hit <ENTER>. The number you enter also never appears on screen. The output correctly gets piped to more.

EDIT2: I guess I didn't quite understand what was going on with the more command. It captures everything going to STDOUT and more's it, right? I don't want that line going to STDOUT. I printed to STDERR instead and now that message shows. The user cannot see what he is typing, though. I could always print out what he typed to STDERR as well, but is a way to show the user what he's typing?
