Please ignore those last two messages.   An offline device just came on and 
those were sent last night.

Thanks.

Thanks.

Re: Conditionally declaring a BOOL in a .m file to be accessed in a .c function

[Ryan Dignard]

This doesn't work?
in the .m file at file scope
BOOL condition = NO;

in the .c file at file scope
extern BOOL condition;
