#COBOL : maintenir, migrer… ou repenser ?
Chez OCamlPro, on explore une 3ᵉ voie avec #GnuCOBOL :
✅ Garder le code
✅ Supprimer les licences
✅ S’exécuter sur PC, cloud, containers
✅ Se libérer des dépendances

GnuCOBOL is seeing a lot of commercial deployments, such as for banking back-end apps, many of which are being migrated from Micro Focus, with users reporting performance improvements as a result. The French DGFIP federal agency moved from a GCOS mainframe to GnuCOBOL

COBOL was the first programming language that I used in a professional environment. Some people hate it, but I still find it one of the best designed DSLs.
There's a reason it's still around, even as an open source variant called GnuCOBOL.

You didn't look very closely at your Wikipedia link, did you? Of the 13 Cobol compilers listed, 4 are cobol standards, not compilers, 5 point to dead links, 2 are H/W proprietary (IBM,MCP), leaving 1, count it, 1 that can be used by anyone. (GnuCobol). And I do not spread mis-information.

Yes, I work both as a COBOL programmer and as a programmer of COBOL (direct on GnuCOBOL, with testing and some input to GCC COBOL and indirect in the ISO COBOL Development Group on the COBOL standards).

It probably would be less prone to mistakes if they used GnuCOBOL, as this translates COBOL into C before compiling according to the docs. Not sure whether all possibilities are covered, and you can run it on Gnu/Limux, BSD, Windows or MacOS… Not the mainframes.

I do and am fixing a COBOL program which is about dynamic data-caching for a bank which runs GnuCOBOL on GNU/Linux while watching the rest of your video :-)
There are definitely jobs for COBOL on distributed systems, too.
