Heh.  Syntactically or not, if $^O contains "MacOS" then
both of the commands will return true.  :-)

I have as of yet to be able to find this.  Either the
bookstore is out (B. Daltons and The BookStop) or it is on
order.  Guess I will have to get the ISBN number and order
it myself.  :-/

The real problem with the contains statement is if Apple
decides to do something like OSMac for the OpenStep Mac and
MacOS for the normal Mac Operating System.  Actually if
Apple just decides to put the word "mac" into what is
returned for both OS's.  It could really muck up a lot of
people's programs, I believe.  Because I'm sure I'm not the
only person out there who has been making their programs
look at the OS to determine what kind of separator they
will have between subdirectory names.  So someone else who
uses the

	if( $^O =~ /mac/i ){
		$thePath = "$theDirectory:$theFile";
		}

will be getting a nasty surprise when Rhapsody in Blue and
Yellow comes along.
