It sounds fine. I noticed that simh.doc needs to be updated and made more
complete, since a bunch of information in it is incorrect, and a bunch of
useful things (like this one) are not mentioned. I'll make a stab at doing
some updates and sending the result to this list. Or is there another way to
submit work?

Ok. This is another example of something undocumented.

It certainly looks that way. Thanks.
