I know I can set up the queue manually from within the data definition
embed point of the procedure but I can't then seem to access its elements
from a list box.

Am I doing something fundamentally wrong?

TIA

You are missing something.
Although the PRE attribute cannot be set directly, you can set it by editing
the local data as text. Define your queue in the normal way (via the
application generator windows), and then go into the text and add the PRE
attribute.

ie:
TabTable        QUEUE,PRE(TabT)
will work
