Interesting interpretation of "old" - as I didn't recognise that style of Fortran code. Some quick checking confirms that recursion didn't get added until after both of the two versions I was formally taught at university - Fortran IV in 1980 and Fortran 77 in 1986.
Incidentally that gives you an idea of the academic delays in those days. I seem to recall the lecturer in 1986 being very pleased to say we were learning the "new" Fortran.
To get a sense of how limited Fortran IV was see here - FORTRAN 66
In my memory any difference between "IV" and "77" is overshadowed by the fact that I had to use punched cards for the former and then had the luxury of using a "glass teletype" for the latter.
Indeed, 1986 was a strange year - as at that same time I was doing other units that had me using VAX Pascal in one and using a Macintosh-based emulation of a PDP-8 to do assembler programming. Neither of these were a "learning" experience as I'd already been hobby programming a Z80 in hex and using Turbo Pascal on CP/M.

Yup…you’re right…what I found was a newer compiler and a not so old Fortran book…
ASM is something I want to learn…but last time I didn’t get past trough Hello World LOL
