hello,
I am sorry to ask, but I can't seem to find this kind of statement in my
book or in the documentation.
$text = defined($ARGV[0]) ? $ARGV[0] : "Hello world";
PS, the end makes sense, that if there is a $ARGV[0] being passed to use
it, and if not use the "hello world", but what is that defined($ARGV[0])
all about?????
If anyone knows where an eg of this is, I would really appreciate.
Thanks
Scott
