One more try...

Hi again,
I implemented the class basic_struct_list_s with a queue as a data member since I want to use some of the built in methods for queues. Is there a way to use these methods (in particular the find methods such as find_first(), find_first_index) when the queue is a queue of classes and other class data member? I tried to do it like this:

< code > 
...
class basic_struct;
      uint lo_addr;
      uint hi_addr;
      string addr_name;
endclass

class basic_struct_list_c;
      basic_struct basic_struct_list[$]
endclass basic_struct temp_struct;

basic_struct_list_c masterΔ]
...
initial
begin
      temp_struct = new;
      for (i=0 ; i<6 ; i++ )
            begin master[i] = new;
      end // for (i=0 ; i<6 ; i++ )
... 
      temp_struct = masterΎ].basic_struct_list.find_first((item.lo_addr<=4) && (item.hi_addr>=5)); ...
end //initial
< /code >

I received the following error:
