As an undergraduate I learned Fortran, Compass, and had a course in
Algol, because "it is the language of the future!" My first course in
High School was IBM 360 Assembly Language (because the school district
had one--that was the year before we got the PDP 1 and switched to basic
on paper tape). Those I knew still using Fortran a few years ago were
doing so because of the parallelized libraries useful on the massively
paralyzed super computers. Sometimes you write in the language used
locally, rather than what you want (e.g., 360 Assembly, Compass, ...).
