This is even more interesting when you note that at address #22E12h
there is a hex string that is the link table for the lib 700h
commands.  There are only 29 entries in it.  It would seem that the
routines that build the menus for libraries are missing the end of one
of the tables (hash, I suppose) for lib 700h.  I've not yet coerced
the subroutines of xMENU to give me lib 2's menu, though.  That would
be interesting, I should think.
