RE: Display schemas

[Ian B]

Thanks for the info. At the moment I am assuming I will create the menus in
my device and download them for use. This will not initially be a runtime
exercise but a setup one. The may change but lets walk before trying to
run.

To send the request for information will I have to target your application
or will broadcast get me the results I need?

At the moment I am struggling to work out a way of holding the xAP message
formats including text in a way that doesn't use masses of memory.

Thanks

Ian
