Fortran, my first real language. I haven’t looked at any since 1993. I wrote whole interactive term screen engineering tools with it. I had a whole system/scheme for how I did line numbering (3xxx for formats, 2xxx for gotos, etc). Some of what I cobbled together is still being used for nuclear fuel assembly design work flow. I have no idea which year’s flavor of Fortran is shown… are implicit variable types based on what letter the variable starts with still a thing? I notice the “real :: …” in the listing… I thought it was kind of quaint feature as I started learning “real languages” after that. All these years later, I kinda thinks it’s clever/original now.
