关于多个文件名匹配后批量输出

我想把读入的文件根据year（i），month（i），day（I）三列分别输出到对应的TXT文件中，输出文件名也是根据这三列命名的，但是匹配输出时是每隔一个文件输出一次（像1，3，5），（本来应该是每日数据分别输出到对应日文件下），不知道是哪里出错

  If (((mod(year,4)==0) .And. (mod(year,100)/=0)) .Or. (mod(year,400)==0)) Then
    daysinmonth(2) = 29
  Else
    daysinmonth(2) = 28

  daysinyear = daysinmonth(month)

嗯嗯谢谢还想请教一下，这里如果我想做个缺省值判断，怎样在读取时跳过有缺省值的这一行呢，我这样写编译能通过，但打印不出结果来。Do i = 1, a
         If (rain(i)==32700 .or.rain(i)==32766) Then
            ! rain(i) = -999
            read(*,*)
            Read (11, *) site(i), lat(i), lon(i), h, year(i), month(i), day(i), pre1, pre2, rain(i)
            print*, year(i), month(i), day(i),rain(i)

1. 我不確定這是不是你的用意
2. "數(numeric)"的運算, 請維持"型態(type)"的一致性: rain(i)==32700.0
