These languages differ from INTERCAL in that their designers were serious

Also noteworthy: RPG --- a language originally designed to look like a notation for the control panel wiring on IBM's relay-controlled punched-card tabulators (the stuff that gave them a monopoly on industrial data processing before World War II). This was particularly obvious in some of the original training material for the language (referring to it by its first name, FARGO), which showed wiring and FARGO statements side by side.

This language has, of course, continued into modern-day use. Apparently it has not yet been extended to support object-oriented programming, but there are rumors that IBM might try that for the next release...
