Description

This code is based on https://github.com/PlummersSoftwareLLC/Primes/tree/drag-race/PrimeCOBOL/solution_1.

I took the above code and made some minor changes to properly compile and run it on a real mainframe.

Contributing requirements

• I read the contribution guidelines in CONTRIBUTING.md.
• I placed my solution in the correct solution folder.
• I added a README.md with the right badge(s).
• I added a Dockerfile that builds and runs my solution.
• I selected drag-race as the target branch.
• All code herein is licensed compatible with BSD-3.

As much as I am genuinely charmed by this, I don't think we can merge it into the solution tree. Not mentioning some smaller technicalities, the main problem is that we have no IBM mainframe to run the benchmarks on. We're now at a point where we really can't merge anything new that we can't include in the benchmark.

May I suggest to open a "show and tell" post in Discussions, and post this there?

Tagging @fvbakel. I imagine you'll like this, too :)

@rbergen Thanks for mentioning this!

@awierzch Great that you took the effort for the IBM compile, I don't have access to such hardware. I did notice that the time is 50 in your output. Is there a dot missing?

It seems GitHub lacks at least one feature, being the ability to convert a PR into a show and tell Discussions post...
Be that as it may, I will have to close this.

No problem, just wanted to share my results and compare GNU compiler on PC with IBM compiler on mainframe.

Yes. I was too lazy to fix this.

I have been putting together some specific IBM mainframe z/OS adaptations so I have included the changes in that:
