Is there such a thing as a global constant (string) in obj-c?

I've been trying to make one. I tried putting it in the main file as
this
NSString *myconst = @"thedatabit";
and that compiles OK. I then declare it as this in a file I want to use
it in:
extern const NSString *myconst;
which again compiles ok, BUT I get this warning when I try to use it in
a message [myObject selectMyString:myconst];
passing arg 1 of `selectMyString:' discards qualifiers from pointer
target type
Usually, these warnings mean it isn't going to work when you run it,
it's just too polite to say so!
I've looked on apple's site, and through the 3 ref books I have but no
joy.
what's the secret?
