Good stuff Geoff.
So, as compactly as I can make it: on mouseUp get the clickline set the text of it to random(99) --works put random(99) into it --does not work end mouseUp shows the distinction between the ability of the engine to set a property contained in a variable, but not use a variable as an evaluated property reference. OK.

This works (as far as I know) with all properties. If a variable contains a reference to something that has properties -- an id, name, chunk, etc, -- then referencing those properties will work. It's a bit tricky. I was going to say that "into" does nothing special, but "of" dereferences the variable to whatever it identifies, but that's not true. For example, this successfully updates the line *after* the one you click: on mouseUp get the clickline add 1 to word 2 of it set the text of it to random(99) end mouseUp So I have to go back to the original: you can set a property on a variable containing a reference, and LC will use the reference. "of" alone isn't the magic word here. _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
