I learned FORTRAN in university in 1990 when I was still in engineering school. I hated the textbook and the instructor was useless, so I bought the Watcom FORTRAN reference manual and taught myself, showing up in class only long enough to get the weekly assignments.
I was in the mechanical engineering department. I wish I had had the option of learning C instead, like the electrical engineers did. I would have had use for it later in life. Never had a need for FORTRAN again.
The language you learn is irrelevant. The point is that you learned a language. I’ve coded systems in almost 2 dozen languages over 30 years. I’m not an expert in any of them but I can write programs in all of them.
I still have to dabble in COBOL and C because we have legacy code in them but I also write in Groovy/Grails because we are writing a new system in it.
No wonder I drink so much.
