CITRAN(ID:383/cit001)

We actually had an online
  system in those days! The terminals were IBM 1052s -- basically, Selectric
  typewriters hooked up like teletype machines. I think the computing center
  was running a couple of IBM 360/65s. I'm not certain ... I was just a lowly
  freshman, and I didn't have access to the sanctum sanctorum in the computing
  center. That was for grad students.

Anyway, the language we used was
  called CITRAN. It was a takeoff on FORTRAN, the Formula Translator,
  but since it had been developed at the California Institute of Technology,
  or CIT, it needed its own acronym. It was a time-sharing system. You
  entered commands, and program statements, from the typewriter. When
  your program was saved in the library, you said RUN and the system
  compiled your code, linked it, and executed it. If you had a bug, you got a
  not very helpful diagnostic message and BETTER LUCK NEXT TIME!
  CITRAN. If you wanted to print an entire program listing, with a
  cross-reference table for all the symbols, it might take 30 minutes, or longer.
  Connect time was limited, so people kept their programs simple and
  short.
