Ritorna una variabile dello stesso tipo del parametro var con tutti i bit messi a 0 tranne quelli specificati.

Parameters:
var Variabile da cui prendere i bit
bit Mantieni i bit a partire dal bit di questo indice (0 indice di partenza)
bits Mantieni questo numero di bit

Parameters:
var Variabile in cui settare i bit
bit Inizia a settare i bit da questo indice (0 indice di partenza)
bits Setta questo numero di bits
x Variabile sorgente da cui copiare i bit (dallo stesso range specificato con i parametri di cui sopra)
