Q: Will A: Regarding calls such as A5 worlds serve several different functions for a 68K application, most notably, access to QuickDraw globals and access to application globals. For a PowerPC application, the system maintains a notion of an A5 world for the purposes of accessing QuickDraw globals because much of the system code depends on locating the QuickDraw globals this way. But there is no concept of an A5 world for accessing application globals, because such globals are accessed by a different mechanism. The way that mechanism works means that a code fragment always has access to its globals. So code that previously had to jump through hoops to get to global data no longer has to do so. Therefore, the calls to |
