2 S4 s5 q$ C4 p7 }# uThe interesting (to me, anyway) part of this question is that the do-variable in an io-implied-do does NOT have "statement scope" the way a DATA implied-do or array constructor implied-do variable do.  With statement scope, the implied-do variable is a new, different variable that inherits only the type of any outer-scope variable (but that type must be integer.)The "i" in the I/O implied DO is the same variable as the line 1 DO control variable and ifort is absolutely correct in complaining about this., pgf90 could support this as an extension, but would need to have the ability to diagnose it (perhaps through a standards checking switch), or else risk being a nonconforming implementation.

The other interesting part is that we do, sort-of, allow changing DO variables, as an extension, but you have to do it by passing the variable to a procedure which then changes it. ifort recognizes the possibility and generates an explicit test rather than a loop count if it sees this.

这个问题的有趣（对我来说，无论如何）部分是io声明的do中的do的变量没有DATA声明的方式或者数组构造函数声明-do变量的方式。 对于语句范围，声明do变量是一个新的，不同的变量，它只继承任何外部作用域变量的类型（但该类型必须是整数。）I / O暗示DO中的“i”是相同的变量 作为第1行DO控制变量和ifort在抱怨这一点时绝对正确。，pgf90可以支持这作为扩展，但是需要能够诊断它（可能通过标准检查开关），否则冒险成为 不合格的实施。

另一个有趣的部分是我们这样做，排序，允许更改DO变量，作为扩展，但你必须通过将变量传递给一个程序然后更改它来完成它。 如果它看到这个，ifort会识别出这种可能性并生成一个显式测试而不是一个循环计数。

已找到问题， 是另外一个模块do循环没有加终结语结束循环，i 的值被篡改，因为我的循环语句用的是i 作为变量，对所有的循环语句都造成了干扰
