Right. This works the same way as in HyperCard or SuperCard: if you set a property, you need to set all of it - you can't set a chunk of a property. (In HC, I generally run into this trying to set one line of a script - same problem, because "script" is a property.) >a) that qualifiers are forbidden when referring to properties - which >is easy to remember once you know it. Not quite: you can't set a particular chunk of a property - you have to set the whole thing at once - but you can get a chunk of a property. For example, "put line 3 of button ID 343" works fine. >b) button contents are properties and also containers like fields, >which is subtle and not that easy to pick up from the documentation. Can you tell me where you were looking? (Buttons are listed in "About Containers, Variables, and Sources of Value", and most of this is explained there, but I may need to add some notes elsewhere.) >Now, I know that menus are buttons in Revo and I'm quite happy about >that, but I am a bit confused about when we use the term 'menu' and >when we use the term 'button'. The "menu" term can be used to refer to the menus in the current menu bar. For example, if the menu bar contains menus "File", "Edit", and "Go", you can say something like get menuItem 1 of menu "Edit" to get the first menu item in that menu. Because menus are also buttons, you can use button syntax to get the same information - but you may need to specify the group and stack the button is in, because if you're referring to it as "button" it can be ambiguous. (For example, you might have a standard button called "Edit" on the current card, so simply referring to 'button "Edit"' might give you the button instead of the menu.) An unambiguous button reference might look like this: get line 1 of button "Edit" of group "myMenus" of stack "Main" This will return the same information as the form using "menu", but you have to know the group name and possibly which stack it's in, so the "menu" form is a little more convenient for menubar menus. -- Jeanne A.
