What is your best practice for setting a script in a script?

[Paul Dupuis]

As some people on this list and the forums have explored in the past, I 
have a interest in creating a Livecode application (stack) entirely from 
a (text only) single script. So there are initially no Livecode objects 
to place a behavior script in. There are initially no buttons, fields, 
cards, stacks, or anything else.

Yes, one of the values of Livecode is an interactive IDE for UI design 
(and refinement), but for this specific interest, it is all about 
creating the UI - in fact the whole app - from a single script.
