I think adding an option to Macro, or creating a variant called MacroExclusive, would be a fine idea. Unfortunately Macro's syntax doesn't lend itself to taking option arguments...

Again, yes, this would be an ideal way to do it, adding an option to Macro to ensure that the entire thing runs to completion (although any apps in the macro that try to interact with the channel's audio will obviously not work, but this is no different than running them in the 'h' extension).

A third option would be to do this using Gosub() instead of Macro(), which doesn't have the limitation of having to pass arguments to the called code... It could be Gosub(context[|extension[|priority[|options]]]).
