Oh wow! thanks - having the sample code will be a huge help. I'll give it a try.

It's perfectly OK, and that's why you were corrected. :) Basically, you'll do the following: * add an instance variable: contents on your instance side, add: initialize super initialize. contents := OrderedCollection new. then for each item of the collection protocol, delegate it, as in: add: anItem ^contents add: anItem. includes: anItem ^contents includes: anItem. size ^contents size. and so on. If you get really tired of adding all of them, just add them as you need them (when the debugger tells you :). If you wanna get really tricky, you can add a #doesNotUnderstand: handler to perform the method on the contents variable, but that can mess up your debugging, so it's better if you don't. -- Randal L.
