Forth. Sorry I misspelled. It was used quite a bit in robotics, and the scientific community. Servo control, hardware control that kind of thing. I loved the language. It unfortunately it is not a practical language for applications.
When I was using clipper we were using 8" floppy's and 14" platters for the hard drives.

I enjoyed using clipper it was so much faster that the dbase interpreter, although I cannot remember all the advantages.

Of course all of us old guys used Fortran. It was powerful, but I never enjoyed using it. Unfortunately, any time I worked on some old goverment program it was either Fortran, ADA or Cobal.

Nerbert, I have seen quite a few old non-analytic analog computers. I was fascinated with them. In some point in my studies I had to design a (not-so-simple) analog computer to solve an easy differential equation. I never actually had to build the thing so I have no idea if it really worked. So I cannot say I actually really used one.

So far @nerbert and @paul when the prize.

@Paul for still using 'Clipper'
@Nerbert for trying to hack an analog computer, by overflowing the input buffer to the integrator.

I had a professor who insisted that if you design a digital controller for a physical system the only legitimate test would be against an analog simulation of the system -- that you were asking for trouble if you used a digital simulation. I don't remember his reasoning but I was skeptical at the time. I complained that even then, back in the early 80s, analog computers were obsolete and you couldn't get repairs for them but he had in mind a sort of Moore's law for analog computing, pointing out that op amps were available at Radio Shack for pennies and you could always build your own. All of us in the class were supposed to learn to program the things but there weren't even enough patch wires to go around. I think the only student who actually got the analog simulation to work was some quiet Chinese guy. I turned in a digital simulation and I think everyone else just blew it off.

Later in grad school I had access to the things for just tinkering around. Some attempted projects required several linked together but for all that I never actually got anything working just right.



Oh the memories ....

Hah, Fortran was the first language I programmed in, on the mainframe at my Dads workplace.

After that I learned Basic and then Cobol.
I last used Cobol about 10 years ago, at Experian (afaik, they still use it).

Short and clear! It's the way that really works I think.
