@ID

[Jeff Kingston]

        How can i get @ID to indent on both left
        *and* right margins?

You can't get it with @ID, you need some other
symbol (easily defined but not currently in
existence).  Alternatively you could descend into
the depths and use

        @ID { ... the display ... |@DispIndent }

which includes a right margin in the display itself.
But I don't recommend this kind of hack, it's better
to do things properly and add a new symbol (see my
previous posting about anticipating everyone's wants).
