If this is in a Perl script you may need to fix a couple of things, I suspect you mean the get_add routine to look like
Code:
sub get_add{
    my @args=@_;
    my $num_args=@args;
    my$last_index=$#args;
    ...
    return $some_value;
}
...
get_add(arg1,arg2,arg3,arg4,arg5, ... ,argN);

Prototypes in Perl are not for the uninitiated, a subroutine is defined with the sub keyword, work around the snippet above and see if it's what you need.

When you call a routine with a list of arguments, you are passing an array to the routine in the special array @_.

In order to determine the number of arguments using a regular expression, you would first have to join them with a sufficiently unique key and then parse them out with the regex, this seems...strange.

Could you specify your problem more clearly, or if it is coursework, move the conversation to that forum filling all the required fields.

   mutate_attributes ( args => $hashref, props => $hashref, type => 'str' )
       A hook for running a second command from within a command without having to use the commandline argument parsing.

       If "type", "uuid", or "primary_commands" are not passed in, the values from the previous command run are used.

   cmp_regex
       The regex to use for matching property key/value separators.

   $ID_REGEX
       The regex to use for matching the id argument (luid / uuid).

   setup_from_args
       Sets up this context object's arguments and key/value pairs from an array that looks like an @ARGV.

   parse_args @args
       This routine pulls arguments (specified by --key=value or --key value or -k value) and properties (specified by --props key=value or --
       key=value) as passed on the command line out of ARGV (or something else emulating ARGV) and sticks them in "args" or "props" and "prop_set"
       as necessary. Argument keys have leading "--" or "-" stripped.

       If a key is not given a value on the command line, its value is set to undef.

       More complicated separators such as =~ (for regexes) are also handled (see "cmp_regex" for details).

   set_type_and_uuid
       When working with individual records, it is often the case that we'll be expecting a --type argument and then a mess of other key-value
       pairs.

       This routine figures out and sets "type" and "uuid" from the arguments given on the command-line, if possible. Being unable to figure out a
       uuid is fatal.
