Hi Wolfgang,
to be honest one of my design considerations was to this work using MetaPost.
But, my knowledge of MetaPost is minimal and it would be involved calculating the positions
of the Frames/boxes and I need to know the sizes of the formatted text, etc
Another approach would be to use layer, but I can not find much documentation about how/if
they can be used inside of a frame.
regards
Keith

There are ways to ignore the spaces at the begin (\ignorespaces) and end (\removeunwantedspaces) of a group but you should rethink first your interface for your commands (why no start/stop commands).
It can be also useful to draw the whole diagram with Metapost and use the TeX commands only to pass the content to Metapost.
