Mphfmbuldjrm! *POP*  Ah!  Now that I've taken my foot out
of my mouth!  ;-)

You are probably right about that!  :-)  Since (in C and
Perl both) when you are printing you usually just put "\n",
it gets a bit confusing which system uses what.  But I
believe that you are right.  And now that everything is
totally mixed up - let me try to correct myself.  (Although
my mom tried to correct me many years ago and that didn't
seem to work!  After all - I'm still a programmer!  ;-) )

The mac does use the carriage return (cr, \r).
The IBM does use the carriage return & line feed together (cr/lf, \n\r).
And Unix uses the line feed (also called a new line, lf, \n).

But in a program they all use \n.
