我需要修改op记录中的值{place}和{other_place}.

#op{
    action   = [walk, from, {place}, to, {other_place}],
    preconds = [[at, {place}, me], [on, floor, me], 
                [other_place, {place}, {other_place}]],
    add_list = [[at, {other_place}, me]],
    del_list = [[at, {place}, me]]
}

但是erlang不允许修改变量.是否有数据类型？
