In the context of these methods, "defined" means that an object has been 
assigned to the variable. In this context, calling "symbolForIndex:" for a 
variable that is not yet "defined" will NOT fail (given a valid 
FSContextIndex argument). A variable can be known by the interpreter, even 
if the variable is not yet defined.

Best,
