Passing global variable to a function which is called by another function

Hi ,

I have three funcions f1, f2 and f3 .
f1 calls f2 and f2 calls f3 .
I have a global variable "period" which i want to pass to f3 .
Can i pass the variable directly in the definition of f3 ?
Pls help .

You can access the global variable directly in the function.
Code:
period="hi"
f3()
{
echo $period
}
f3
