hdo and vdo are now fully functional,
using exactly the same syntax as do.

The meaning of "vdo ... done;" is simple.
Remove the "v", and execute the resulting
command "do ... done;" in every view (context).
Using the "exec" command permits you to
execute statements, questions and assignments
in all views.

vdo exec od {propositionlist} done;

The meaning of "hdo command ... done;" is
to walk the hierarchy as specified by

from initial concept
to final concept
with path

executing

do command od cname done;

at each concept (or individual) in the path.
Cname may be any of

.. current genus of current concept
. current concept
... current species|unit of current concept

"od ." is the default, and need not be stated
explicitly. For example, this command prints
an alphabetical dictionary of all concepts and
individuals in the hierarchy.

hdo define from existent with alpha done;

When you do this, don't forget to read in all
the definitions from KEHOME/kb/*.def first.

All of the available hdo commands are displayed
when you enter;

hdo ? done;

You can find further details in today's updated
MKR/MKE Tutorial.
