Uncoupling More Than 20 cars?

I have a consist with over 20 cars of various kinds. The UNCOUPLE command appears to limited to 20 cars, I assume counting from the engine. So if I wanted to make a cut a car #30 I would have to first cut away 20 cars and then cut at #10. Is this a correct assumption?

Try this command:

Decouple DLX,<kuid2:160293:100120:2>

It decouples up to the 99th car in a consist.

Finally tried the Decouple DLX and it did exactly what I wanted. THANKS!

Thanks for that info Pendolino, been wanting that for a long time.
Cheers,
Mike
