Z/OS COBOL V6调用DLL
我主要是一名 C 开发人员。我有一个示例 COBOL 驱动程序，它在 z/OS 中调用我的 C DLL。
当我们使用预链接器和 IMPORT 语句在 DLL 内定义 API 时，COBOL 驱动程序在 z/OS COBOL V4 中工作正常。
对于 COBOL V6（和 V5），不再支持预链接器（以及大量其他更改）。
如何让 COBOL 识别我的 IMPORT 语句以了解 DLL 内的 LONGMIXED API？
COBOL 调用如下所示：
CALL
'PBFNTerminate' USING
BY VALUE NULL-POINTER,
我的 COBOL 程序是使用 RENT,DLL,PGMN(LM) 编译的。
我尝试简单地将 DLL 创建中的 IMPORT 语句包含在 BINDER 中，但它们似乎被忽略了。我有 DYNAM(DLL),CALL 作为 BINDER 参数，但我仍然得到：
IEW2456E 9207 SYMBOL PBFNTerminate UNRESOLVED. MEMBER COULD NOT BE INCLUDED FROM THE DESIGNATED CALL LIBRARY.
如果我使用 DYNAM(DLL),NCAL 运行 BINDER，我得到
IEW2454W 9203 SYMBOL PBFNTerminate UNRESOLVED. NO AUTOCALL (NCAL) SPECIFIED. NAME SPACE = 3
然后是 S0C1我试着跑。 我认为我缺少一个步骤或参数，但显然我不知道它是什么。
附带评论，COBOL INTERLANGUAGE COMMUNICATIONS 指南似乎是在 COBOL V5 和 V6 之前编写的： https://www.ibm.com/docs/en/cobol-zos/4.2?topic=answers-interlanguage-communication
I am primarily a C developer. I have a sample COBOL driver that calls my C DLL in z/OS.
The COBOL driver was working fine in z/OS COBOL V4 when we used the Pre-Linker and IMPORT statements to define the API’s inside the DLL.
With COBOL V6 (and V5), the pre-linker is no longer supported (along with a myriad of other changes).
How can I get COBOL to recognize my IMPORT statements to know about the LONGMIXED API’s inside my DLL?
The COBOL call looks like:
CALL
'PBFNTerminate' USING
BY VALUE NULL-POINTER,
My COBOL program is compiled with RENT,DLL,PGMN(LM).
I tried to simply include the IMPORT statements from the DLL creation in the BINDER but they seem to be ignored. I have DYNAM(DLL),CALL as a BINDER parameter but I still get:
IEW2456E 9207 SYMBOL PBFNTerminate UNRESOLVED. MEMBER COULD NOT BE INCLUDED FROM THE DESIGNATED CALL LIBRARY.
If I run the BINDER with DYNAM(DLL),NCAL I get
IEW2454W 9203 SYMBOL PBFNTerminate UNRESOLVED. NO AUTOCALL (NCAL) SPECIFIED. NAME SPACE = 3
And then a S0C1 when I try to run.
I’m thinking there is a step or parameter I’m missing but obviously I don’t know what it is.
Side comment, the COBOL INTERLANGUAGE COMMUNICATIONS guide seems to be written pre COBOL V5 and V6: https://www.ibm.com/docs/en/cobol-zos/4.2?topic=answers-interlanguage-communication

发现问题了。至少对我来说，PLKED 步骤默认为 NOUPCASE。在 Binder 中，我必须将 CASE(MIXED) 添加到 PARM 中。最终的解决方案是：PGM=HEWL,PARM='DYNAM(DLL),CASE(MIXED)'。
Found the problem. At least for me, the PLKED step defaulted NOUPCASE. In the Binder I had to add CASE(MIXED) to the PARM. The the final solution was: PGM=HEWL,PARM='DYNAM(DLL),CASE(MIXED)'.
