OpenCOBOL 找不到 运行 程序的外部模块
OpenCOBOL can't find my external module to run the program
我正在尝试使用 OpenCobol 创建一个 COBOL 程序，该程序在进行计算时具有外部模块，然后使用 CALL 将结果返回到主程序中。但每次我尝试 运行 程序时，它都说找不到模块。我已经将我的模块从可执行文件更改为程序类型“模块”，并将模块路径添加为库路径，但到目前为止没有任何效果

我不是 OpenCobol 的用户，但是，根据他们在第 7 节中的手册，有很多方法可以完成您想要的。
但最简单的是在一个命令行中静态编译和link主程序和子程序：
cobc -x Project2.cbl Program3Call.cbl
在大多数 COBOL 实现中 CALL 的正常方法是仅指定模块名称 - 没有路径或扩展名。
然后你要么做“静态链接”（如斯科特下面对 OpenCOBOL/GnuCOBOL 的回答，只需在命令行上指定所有源并使用 -x [fat 可执行文件] 或 -b [fat 模块，然后可以用 cobcrun] 调用，通常用 -static);或者做“动态链接”（所有模块的单独编译）并在配置文件中或通过环境变量指定模块路径。对于 OpenCOBOL/GnuCOBOL，这是 COB_LIBRARY_PATH。
这个例子适合我。
请记住，dll文件例程模块的名称必须与例程名称相同。
无需重新配置 OpenCobol 路径库。
