}  I've been trying to find a way to list all of the mac specific Flags and

}within MacPerl or how to install them.

Provided you're using a PPC machine, it's not really necessary to use
XFCN's to do this any more, thanks to Mac::Files.  The size of the data
fork has always been easy:

$dsize = -s $file;

where $file contains the path to the file.  The size of the resource fork is
a little harder to obtain:

        $has = Mac::Files::FSpGetCatInfo($file);
        $rsize = $has->{ioFlRLgLen};

and you can also get a lot of other information out of the structure
returned by Mac::Files::FSpGetCatInfo, like  the Finder flags, type and
creator:

        $finfo = $has->{ioFlFndrInfo};
        $type = $finfo->{fdType};
        $creator = $finfo->{fdCreator};
        $flags = $finfo->{fdFlags};

It's a good idea to have a copy of Inside Macintosh around when using
these.  There's an online archive at
<http://devworld.apple.com/cgi-bin/ftpchooser.pl?partialURL=Technical_Documentat
ion/Inside_Macintosh/>

I don't think Mac::Files works on 68k machines, and I don't know whether
Matthias is going to compile them into a future BigMacPerl or not.
