“Ladies and gentlemen.

I was just successful performing a gdb-cobol debugging session hosted on an Intel computer where I remotely debugged a COBOL program compiled and running on a target IBM System Z.

I think I will leave it to others to provide a sense of just how big a deal this potentially is.”

Yes, it’s a big deal. Very. #gcobol #cobol
