One way to do it (the way I generally use) is through the MPW Shell, 
available from Apple for $99 ($49 for an update if you have an older 
version) in E-T-O #23, also bundled in the MetroWerks CodeWarrior 
distribution, and the MacPerl tool, available from CPAN (you'll see 
there's a MacPerl_appl and a MacPerl_tool, or something like that).  
Gives you a shell interface to the MacOS.

For my perl script "retrieve.pl", a line like the following works like 
you'd expect it to from a Unix command line, when entered into MPW:

perl -s retrieve.pl -match=exact -- wheel

where I'm setting the variable $match to "exact" and setting @ARGV to ( 
"wheel" ).

Another way is to have a separate file with the args, and require it in 
your script... then you only have to change the extra file and not the 
original script when the args change.

Another way:  If the arguments are filenames, save your script as a 
MacPerl droplet, and then drop the files on it.  Droplets set @ARGV to 
the files and folders dropped on them.

Yet another way:  ask for the args through <STDIN>, which is the MacPerl 
console window by default.

Hope this helps.
