yes .... but when I added a line after the while like this:

while(<>){        #reads lines until end of file or a Control-D
   print "$_";    #prints lines back out
}

print "done";

why don't I see the 'done' after Ctrl-Z?

I think this is *x system. The "Ctrl+Z" is mapped to the suspend signal (SIGTSTP). This suspends the execution of the program. You can restart the execution of the program by : fg %1 (if this is the first task to be suspended). Actually, "Ctrl+Z" does not bring you out of the while loop. On starting it again, you will still be inside the while loop. You will have to press "Ctrl+D" to come out of the loop.
