I am want to break down the following code that can have any number of vars
being passed:

  c_routine("name_1", 2, 3, 5, 0,9, 1, A, b, -1.5, 1.2, 100000, 0.03, 0, 0,
1, 0, m, l, var_name_1, var_name_2, var_name_3, var_name_4, var_name_5,
var_name_6);

I only want the passed vars.

           my ( $nuts, $line ) = split /\(/;
           my @passed_vars = split /,/;

Also is it possible to get only the vars following ", m, l, " through ");"?

Thanks,

Jerry
