Sure. But $\ isn't the input separator. I ran a couple of tests and got some strange results when changing the input character. How did your tests turn out?

I meant $/ ...
sorry

Ah ha - figured out the 'strangeness'. I effectively had a <STDIN> statement in my test program (ie. "Press return to continue" type code) and I absentmindedly was trying to indeed hit the return key to keep going. Since I'd changed $/ I also had to add the new character string into the prompt before it would recognize it.....

PinkeyNBrain gets a star from me for sparking my creativity.

print "Type everything then send EOF.\n\n";
$/ = "\x04";
my $in = <STDIN>;
print "===\nYou said:\n$in\n";
exit(0);

So with that I was able to type as much as I wanted and hit enter and everything, and it wouldn't return to $in until I hit Ctrl-D (or Ctrl-Z if this was a DOS-like system).

[kirsle@firefly ~]$ perl test4
Type everything then send EOF.
