Yes, most everything related to objects in Transcript comes down to 
getting and setting properties.

One of the most valuable ways to learn Transcript is through dissection, 
reading other people's scripts, looking up in the Transcript Dictionary 
any keywords you don't recognize, and then playing around with what you 
learn there.

The "set" command sets the value of a property, and if you look at the 
one line in the handler the property is sets is "rect".

Look up "rect" (the longer form "rectangle" is an accepted synonym) in 
the Transcript Dictionary, and after reading that entry follow the "See 
Also" links to other entries that seem of interest to you.

With a few minutes in the dictionary you will have mastered setting the 
rectangle of objects, ready for the next thing to learn....
