I just set num_days in the example to show you how a shell variable is passed into the perl program. Typically you would be doing some sort of calculation or assignment from the script's arguments into num_days.
We then put $num_days on the end of the perl command line and this can be accessed as ARGV[0] from within perl. ARGV[0] here isn't a parameter to the csh script but rather the first parameter passed on the perl command line.

-a authname, --authname=authname
The user to use for authentication (defaults to current user).
-r realm, --realm=realm
The realm to attempt authentication in.
-p password, --password=password
The password to use when authenticating to server. Note that this parameter can be seen in the process list. Use with caution!

-f file, --execfile=file
Instead of working interactively, run commands from file file and exit when done.
