Thanks Bjarne,
for the eye-opening examples of property access; I'm sure they can be
useful.
Until now, I had just used sprite(1).propname to get the value.
However, the direction of my question was more about the OOP "ethics" of
accessing properties directly, and how to find the balance between
encapsulation on the one hand, and avoiding redundant code on the other.
I'm trying to decide how seriously I should take the school of high
object integrity in Lingo. When I do, I feel I'm doing it for form's
sake. Still, I'm hoping that adhering to these strict and seemingly
silly rules will someday take me to the moment of OOP enlightenment that
some talk about.
regards, Clars
