I am working on an FKEY that will need to store four byte of data between each invocation. Without that storage, it simply won't work. The question is, how do i do it? The storage must be global, independent of which application is in the foreground under multifinder, and should stay around even if the user launches or exits from an application. Thanks for any help I can get. -- _____________________________________ ____________________________________ | David Byers ||SnailMail: David Byers | | || Ryds Alle 9:204 | | c90davby@odalix.ida.liu.se || S-58251 Linkoping | | byers@nanny.lysator.liu.se || SWEDEN | `-------------------------------------'`------------------------------------'

I have the same problem for an FKEY and while I haven't tried it yet, I think
the answer is to create a resource for the System (or your own file) called
"mLng" or somesuch. If it exists, then use it as a scratch pad, if it doesn't
exist, then create it. Use ID 1000 or somesuch and you should be set... (I hope)
Let me know if this works or if someone else comes up with a better way, as
I need to use this too. (ever want an interactive profiler that can "zoom in"
on the most used memory locations and display a graph from a DA while your program
is running?).

Try a simple data-fork file in the System Folder. Or, better, in the Preferences folder (System 7). If that makes you ill, get a handle to yourself, set your globals, and call ChangedResource on yourself. (UpdateResFile might be necessary as well, but probably WriteResource is as far as you will have to go.) But PLEASE don't go adding resources to the System file!
