I ve a bit of missunderstood about functions: as i read the functions works:

basically 2 types:  
named (can be lonely)  
unamed (need and object)

- can i define a function wherever i want? ( \_root, MC…) and call it from everywhere?, before or after i created it?

- if the variables of a function are local variables of that function. How can i store the result of a calculation of the function, in a variable outside it?

apologize my poor english  
Regards!
