I understand the exigencies of cross platform support. That said, I miss most of all the menu handling in HC, as opposed to the button group in LC.


The creation of a custom menu with associated menuMessages was clean and clear, and those menuMessages could be invoked via "doMenu", but did not require it. The menuMessage handler references were loaded upon menu creation, accessible like ordinary handlers with a simple call.


But you know all this. I am obviously misunderstanding your statement above.

Did Apple ever release a version of HC with its IDE written in HyperTalk?

I suppose it could be a matter of taste, whether one writes scripts that 
invoke menu items that invoke commands or writes scripts that invoke the 
commands directly.

Personally, "quit" seems simpler and more intuitive to me than "domenu 
quit".

Reliance on doMenu as a language design element also introduces 
inconsistencies:  what happens when you make your own custom menus and 
still need access to a command normally handled by doMenu?

Even if HC allowed that, it would seem odd (at least to me) to have to 
invoke a menu that doesn't exist.
