- First off, thanks to all who have helped before (your names are in my
- rolodex as ehlpful people -- perhaps some fear is in order...)
-
- I have a VBL task that needs to manipulate a quickdraw global. BEcause
- the VBL may either be launched from an init, or from a cdev after launch,
- I do not know of a single A5 that I can garuntee as valid whenever the
- init runs, so I do not know what value to glue into my queue entry.
-
- Assuming you needed to get to a quickdraw global in a VBL, and the
- launcher might just be an init, whose heap dies when the finder stsrts up,
- or the launcher might be a cdev, whose A5 is the same as the Finder (right???),
- what would you do? Is there something I have missed in the pages of the new
- Inside Macintosh?
-
- On a partially related question, is there any problem with using the new
- popup menu CDEF thoughtfully included with System 7 in a cdev?
-
- Thanks for any help,
-

- Of course reality is an option. Not always a good option, mind you,
- but an option none the less.
