loop for demo

[Don McLane <dmclane-at-ieee.org>]

Is there any way to write a script to run EMC in a loop that clears 
Backplot and runs a program over and over?

I'm setting up a display for local event (Launch of UW Institute of 
Technology, state governor, etc. will be there).  I don't have a mill, but 
do have a servo motor test stand that displays some motion.  The demo files 
that come with the BDI will be sufficient.  But I'd like them to run 
continuously.  Any ideas?

Thanks,
Don
