Yes (when using the MPW shell and the MPW perl tool.  Just like Unix.
Almost.)
You can easily say
    perl PerlScriptName.pl -file myfilename ...

presuming perl is on your MPW command path.  The MPW perl tool installation
script ensures that the path is set up correctly.

to say
   PerlScriptName.pl -file myfilename    (...)
requires some special code at the beginning of the script.  See chapter 22,
p. 324 of the book "MacPerl: Power and Ease" or the html version of the
book at http://www.ptf.com/macperl/ptf_book/HTML/

The Mac OS, of course, does not have a command line.  However, you can
_drop_ files onto a MacPerl script droplet and treat these as you would any
other argument.

Your first example is an example of your second question.  But, yes.  Both
in MPW and standalone MacPerl.

(Actually, note that the interpreter _always_ runs separately on *nix, even
if the script is on your path; you just don't call it directly and don't
see it running. But it _is_ running.)

Under MPW perl, put the script on your command path and follow the
directions given in macPerl: Power and Ease as referenced above.

For the standalone MacPerl you can make a droplet (which looks and feels
like an application but needs the full MacPerl distribution available) or a
MacPerl runtime (which incorporates the required portions of MacPerl into
the runnable script "application".  Droplets and Runtimes are documented in
chapter 8, p. 122 of MacPerl: Power and Ease.
