Enterprise Cobol - Reconciliation between Listing line number and Source line number

We are in the process of deploying the implementation of a DevOps approach on the mainframe.

In particular, we want to implement code coverage and unit test follow-ups (automated tests).

Market tools, especially the SonarQube tool, work with the Source code line number, but code coverage tools typically return the line number in the compilation Listing.

We would like to have an utility that transforms a compilation Listing line number into a Source code line number.

We would be able to develop such an utility (this is a simple file pairing problem), but we believe that this utility should be provided with the COBOL compiler in such a way that it is universal and usable in any environment for any solution for each of the customers.

This utility should also take into account the detection of dead code (unreachable code) and uncompiled code (code excluded by conditional compilation directives).

An alternative would be for the COBOL compiler to keep track of the Source code line number and be able to return it to the compilation listing level, but that would mean that the COBOL compiler would be the only source code processing process, which doesn't This is not the case when using pre-processors (Db2 or CICS) which themselves transform the initial source code.

The utility should produce a file containing at least for each line of Listing the following information:
- Listing line number
- COBOL division: Identification, Environment, Data, Procedure
- origin of the line: main source, COPYBOOK, pre-processor ...
- Main Source line number (null if the line does not come from the Source code: COPYBOOK origin, pre-processor ...)
- kind of the line: comment, non-procedural (without associated executable code), dead code, code excluded from compilation

    The code coverage and SONAR context is just a use case.
    We believe there may be many other cases where tracing / tracking the source code line number may be necessary.

    With modern tools, the developer rarely consults the compilation listing, and he is satisfied with just knowing the return code of the "build", (which poses other problems because then he does not take cognizance of the Warnings such as for example the messages emitted by the RULES).

    Regarding your answer, what tools do you recommend to deal with code coverage with restitution of the line number in the source code rather than the line number in the listing?

    This RFE is being rejected with the suggestion of using a code coverage tool that's compatible with Enterprise COBOL.
