As far as I know, the # (dump) instruction is undocumented - I originally
found it by accident and it's very useful. Even better, and the one I
meant to mention first, is the asterisk (*) which can be used to show a
saved list in a PUTLIST format and also works with FRAME entries to show
the attribute lists.
Both # and * operate from the BUILD directory window and will write to
the message window.
Hope it's useful
