WML <refresh> Tag
The <refresh> task is the simplest task that actually does something. Its effect is simply to perform the variable assignments specified by its <setvar> elements, then redisplay the current card with the new values. The <go> and <prev> tasks perform the same action just before displaying the new card.
The <refresh> task is most often used to perform some sort of "reset" action on the card.
