Ok.  First, create a copy of perl.exe called #.exe.  Second, create an empty
file called $$.bat.  Now, your .bat/perl code looks like...

	# %0.bat %1 %2 %3 %4 %5 %6 %7 %8 %9
	$$ ;

	Your Perl Code Here

At least, this works under DOS 3.2.  It relies on the non-nesting nature of
your script.bat and $$.bat files.
