dynamic - 调用COBOL程序的默认模式是什么？静态还是动态？

Question

我最近参加了一次面试，被问到这个问题:

How are cobol programs are called when no compiler option specified? Static or dynamic?

我的答案是动态的，但我不确定正确的答案是什么。

Answer 1

How are cobol programs are called when no compiler option specified? Static or dynamic?

这似乎是一个棘手的问题，因为默认值是:CALL 文字 是静态的，CALL 标识符 是动态的。

参见http://publibfp.boulder.ibm.com/epubs/pdf/igy6pg20.pdf ,适用于 z/OS 的企业 COBOL，编程指南，版本 6.2，SC27-8714-01。

第338页，DLL

Default is: NODLL

Pge 340，动态

Default is: NODYNAM

第 498 页，进行静态调用

When you use the CALL literal statement in a program that is compiled using the NODYNAM and NODLL compiler options, a static call occurs. With these options, all CALL literal calls are handled as static calls.

第 499 页，进行动态调用

When you use a CALL literal statement in a program that is compiled using the DYNAM and the NODLL compiler options, or when you use the CALL identifier statement in a program that is compiled using the NODLL compiler option, a dynamic call occurs.
