Re: Executing JavaScript from AllegroServe

(Sorry for the delay in replying)

That's it, except that I want AllegroServe to return some JS code, without 
bringing up a new web page.  IOW, I want it to modify the JS objects 
without going to a new URL.  I haven't had a chance to look at the HTML 
TreeView objects that David listed, but I will soon.  I'm thinking that 
might be the way to go.
