[Therion] Height numbers in square boxes

Yes the Missouri set would be even better.

The therion book indicates that height can be added to pit or wall:pit
p29
"height <value> ▷ height of pit or wall:pit; available in METAPOST as a
numeric variable ATTR__height."

I guess that would also make sense for a floor-step, however if you try
it you get the error
-height not valid with type floor-step
When you use an altitude on a wall it adds a label but does not seem to
with pits maybe the same should happen with steps and pits, currently I
have no idea what happens to the height attribute on a pit. Looking at
data.mp the l_floorstep does have a ATTR__height and it is set to -1!

Yes I'm having similar problems to you defining a box, my skills are
generally limited to copying existing definitions and adjusting them
slightly. My guess is that it is not a metapost, it is tex as it is a
label, in tex you can put a box round text  with

\fbox{4}

but how or if you can use that in therion I do not know.

It is a problem that is interesting me, as I think it is something that
I might want to use.
