In a cobol program two copy books are used.

But these two copy books are present in both PROD copylib as well TEST copy lib.

But during compilation of the cobol program i want the one copy book from (old version)Prod copylib and another from (new version)test copylib.As i mentioned both copy books are in both prod and test copylib.

It was a interview question in value source technologies.But i answered that use one copylib that contains versions need for both copy books.The interviewes is not satisfied.

Is there any possiblility of getting this solved in other way?

Thanks in advance

The very first question you should have asked is - do you want to know about version control tool/s? Is your question related to them, then is it about Change Man or endeavour?

Once you get the answer for that and if it turned out to be "change man" I(Anuj) could give you a direct answer, however, in general you could say at the time of staging/compiling you will pick the versions of your choice for copybooks.

Hope this helps.

Sir,

The interviewer is not interested in version control tool.During compile using IGYCRCTL in JCL itself.

I worked for around 3 months in a project where changeman is the version control tool.I am aware that we can give only the copy books changed while staging.

But now i am using endeavour.Please help me is there any similiar way we can do it endeavour.

Thanks

You can tell the cobol compiler which version of the copy you want to use by specifying the library name in the copy statement.
See this paragraph and this one, both from the COBOL Language Reference.

Never used that before but I knew it existed. I'll have to check in depth tomorrow at work...

Version control tools are just an easy interface for compile/link-edit your programs - in "back-end" they also generate the JCL using the IGYCRCTL.

Martial,

Do you think, there will still be sites which are following the rules told in first-link of your post, I just wonder!

Luckily enough, this is an interview question.
It most certainly won't work when compiling from a version control tool, so I hope nobody uses this option.

Yup, that's what I thought. Because having a "hard coded" reference in a program for some library did not sound like a "future compatible" code...

Take care icon_smile.gif

The asker's answer is correct. If interviewer is not satisfied, we/COBOL can't help.
