Hi,
Thanks for the responses. I was hoping for a "just put a -> after the variable and it'll work" type of answer. DuaneB: Your comments are interesting because I'm basically rewriting my original working sketch (which also includes buttons, LED displays, a web server and thermostat control) to make it object oriented. One of the first things that occurred to me is that, although the OO code is more understandable, extensible and compact from a coding perspective, I'm using more RAM. I'm not sure about more Flash but it wouldn't surprise me. pYro_65: the paradshift link greatly increased my understanding of this subject - Thanks!
