- 1. Control-H generates the same ASCII character as the forward delete
- key on the extended keyboard. Should my application perform a delete
- (i.e. Clear) when Control-H is pressed or should I trap that event?
-
- 2. A user opens a file on a locked disk and makes changes to it.
- (Alternately the user locks the disk while the file is open.) When
- the user attempts to save should I
-
- a) Simply post an error message saying the disk is locked?
- b) Check that the disk is locked before every save (If so how?)
- and if it is do a Save As instead?
- c) Check that the disk is locked before every save
- and eject the disk and post a dialog asking the user to unlock
- and reinsert it?

- 3. Can an original Mac 128K and/or Mac 512
- run a system that adds the features described in Inside Mac IV?
- particularly the List Manager, UpdateControl, TrackBox and ZoomWindow
- toolbox calls, and the automatic scrolling in TextEdit? If so what's
- the earliest system that supports these extensions? 4.0? 4.1?
- Similarly what's the earliest system and/or ROM version that support
- the non-Color-QuickDraw toolbox calls from Inside Mac V?
- Particularly SetCmdKey() ? Is there any easy rule of thumb to tell
- whether a particular call is supported by a particular system
- version or ROM version without having a Macintosh with such a
- system and ROM to test it on? Note that I'd like to know this
- at compile time, not runtime.
