--- Comment #4 from Simon Sobisch <simonsobisch at gnu dot org> --- > If CHANGED is not important, we can emit a not-implemented warning and always > print, changed or not. This is what GnuCOBOL does, leading to: * existing code compiles * code does run, it "just" creates too much output While there _is_ the option that some monitoring checks for the "changed" part in its output and "what is possible is done somewhere", this is so unlikely that we decided to go with 90% until someone says he needs the runtime support for the missing 10% as well.
