Dear All
I am trying to convert an existing simulation application which has been
written in MODSIM (an object oriented Simulation Language) to Delphi.

Can anyone tell me how I can set up a Queue of Objects (or a list of
objects) in Delphi.

These objects are things like Cars e.g. have a methods and attributes
....and I want to have the ability of doing things like;

FOREACH DummyObject in Queue1
    Print DummyObject.name
    Print DummyObject.speed
END FOREACH

so that way I go through the whole list and print the names and speeds of
every single car (there could be as much as 10000 cars in the Queue)

Also, is it possible to have a Queue of Queues or a List of Lists

Many Regards
Behrooz

The object you want is either a TStringLIst or a TList.  TStringLIst allows you
to store an object along with each string.  That object can be anything that
inherits from TObject, which is every object in Delphi.  TList lets you do that
as well, but with TStringList you can have some easily searchable label
associated with each object.

If you had a TStringList of your TCar objects, your code above would look like
this:

        for i := 0 to (carList.Count - 1) do
        begin
                MyPrintFunction((carList.Objects[i] as TCar).name) ;
                MyPrintFunction((carList.Objects[i] as TCar).speed) ;
        end ; // for i := 0 to (carList.Count - 1)
