What? No PL1 Ed? ?
Actually, that was only on IBM machines (we had an IBM mini-mainframe in college named Kermit). PL1 was really just a combination Fortran and COBOL. In addition to the ones you listed, we had to learn Assembler, C and RPG3 too! More languages came along once I was working at a defense contractor (CSC) back in 1984 (ADA, Lisp, DCL, etc.)... The guidance system for the Tomahawk cruise missiles was written in... *Oops!* I'm still not allowed to tell, sorry! ?
