Jeanne, thanks for your interest: I did you an injustice. I have to admit that I read this at the beginning of my work with Revolution and then didn't look at it again. If I had, I would have known about the 'customKeys' property. There were only a few things I have wanted to know (so far) which aren't in that article, and I found them by experiment:Graham, have you read the "About properties, custom properties, and property sets" topic in the documentation? I think it might answer some of your questions in this area.
1. Do I get an error if I try to access a property that doesn't exist, or is perhaps the new property created, as it is with 'set'? The answer is "no" and "no", and furthermore no 'getProp' message is sent, but if the non-existent property is part of an assignment statement, like
get the myMysteryProperty of grc "gr1"
the variable (in this case 'it') becomes empty.
2.What kind of list do you get from the 'customKeys'? The answer is a return-separated list (each property name is on a different line).
