Ese ciclo nos permitirá repetir un grupo de instrucciones un número determinado de veces.El ciclo For-Next debe tener una variable que será nombrada como Contador, y ese contador debe tener un valor inicial y uno final, para indicar cuántas veces se repetirá un código.El contador irá aumentando su valor en cada ciclo o cada repetición que se haga. El bucle For-Next es una de las instrucciones más útiles al programar en VBA. Each time within the loop, it would display a message box with the value of the LCounter variable. This is a great way to loop through any number of rows on a worksheet. Therefore, if the first value of iFib_Next were greater than 1,000, the loop would not be executed at all.
