使用声明调用模块

Question

我正在尝试使用

的几个模块

Use Strn, Mindy, Info

然而，GNU编译器抱怨

Syntax error in USE statement at (1)

Answer 1

如果我理解标准，每个模块必须独立。所以你应该

use Strn
use Mindy
use Info

而不是

Use Strn, Mindy, Info

以下是来自WD 1539-1 f2008草稿的复制粘贴，您可以看到每个使用声明只有一个模块名称。

use-stmt  is USE [ [ , module-nature ] :: ] module-name [ , rename-list ]
          or USE [ [ , module-nature ] :: ] module-name ,
          ONLY : [ only-list ]

module-nature  is INTRINSIC
                or NON INTRINSIC

rename         is local-name => use-name
               or OPERATOR (local-defined-operator ) =>
               OPERATOR (use-defined-operator )

only           is generic-spec
               or only-use-name
               or rename

only-use-name is use-name
