But it's a 'working' starting point. \startJSpreamble functions used now function do_digit(d) {console.println("do_digit("+d+") at page "+[this.pageNum]); Stack[Level] += String(d); do_refresh(Level) } var Stack = new Array(); var Level = 1 ; function do_refresh (i) { vv = this.getField("Stack.".concat(i)) ; if (vv) { vv.value = Stack[i] ; vv.readonly = (i!=Level) ; this.dirty = false } } \stopJSpreamble > and the field never changes.
