Rich_A.
He's done a lot of the "RUN" <feature> type of
scripting. Read through some of his posts and
hopefully you'll be able to glean a few ideas
that may help.
At last report, Rich was working on a full
featured command line program that would enable
your Hal to walk around, in and out of view left
to right foreward and backward. Run practically
any app on your system, change clothing, etc.
I'm sure he'll let us know when it's ready.
