Re: Err, 'C' is about twice
Well Cobol is over 50 and still ticking.
Works well too, unless you insist on running it on a toy computer, where it invariably is converted into horrible security-bug riddled 'C'* before being compiled.
This safety is conferred partly because mainframes don't look like Unix usually (which confuses the Young and Hacky) but also because no-one paid attention in the one semester they took of Cobol 101 and so remain terrified of the language - which has NO semi-colons or double equal sign nonsense.
And if one eschews the hideously dangerous Dynamic Linking philosophy, one is gold.
Write all important stuff in statically-linked Cobol and only run it on an airgapped mainframe. You know it makes sense.
