In 1987, I was in my pre-final year of Mechanical Engineering degree. Computers were new, having been introduced in India in early 80's, and programming was entirely new to me. Getting hands onto a computer was indeed rare, and somehow I got hands on a VAX VMS mainframe system. Compiling, linking, running - were all new. I had just learnt that there's something called as a 'file' - because the only files known were office files. And we were writing 'files' to implement the Newton Raphson method, the Regula Falsi method, etc.
Against this backdrop, GOTO was indeed a saviour, because what it did was indeed magic. And all my files were not more than 70 or 80 lines long, as it was college-level code.

It rather depends whether you are talking about the 'vanilla' GOTO statement. which exists, in some form, in most languages, and at least arguably has a limited number of valid uses, or Fortran's 'Computed GOTO', which I can only recall using once in my life as a Fortran programmer, and which is probably one of the most bug-prone programming constructs ever devised!

One of my Computer Science professors back in the late '80s had the memorable quote: "Be wary of anyone who refers to Fortran77 as 'the new Fortran'."
|
|
|
|
|
During my student days, we wrote a spoof Fortran language proposal to add the COMEFROM statement to replace the much derrided GOTO

The problem with that is, whoever of the old gurus said (in the 1970s): 'I don't know what languages will look like in year 2000, but they will be called Fortran!'
Fortran 2023 has very little to do with the Fortran I learned in my studies in 1978-83. (Fortran was limited to the first two years.) I do not recognize today's Fortran as anything even vaguely resembling what I learned back then. If I were to teach it, I would first have to learn it as a new language.
Is GOTO at all a relevant statement in modern Fortran?

Agree.
As I remember, FORTRAN 90, which I came across in the late 90's had the concept of Pointers. Today's FORTRAN may even have the concept of Classes. And the GOTO may be like "Hey GOTO, GO AWAY FOREVER".

Yes, it's good to know .. and the comment on their page adds some reasonable explanation:
"... Less than half a year ago, the new ISO Fortran 2023 definition was published. ... Fortran appears to be fast, having native mathematical computation support, mature, and free of charge. Silently, slowly but surely, Fortran gains ground. It is surprising but undeniable. ..."
So, it's time to find my Fortran FFT code which I used back then ...

From what I've heard, its the NAG, the UK-based Numerical Algorithms Group, which has mainly been responsible for the continued usage of Fortran.

I would guess it has to do with supercomputers in large part. Fortran has been used with them for decades and still is. Nvidia has support for CUDA in Fortran and that makes it possible to adapt code to run on GPUs which almost every modern supercomputer has these days.

Quote: I would guess it has to do with supercomputers in large part. That's possible indeed ... Perhaps surprisingly, there is a lot of up-to-date information, for example Fortran - Wikipedia, it makes me also think about possible use in LLM training ...

When I learned C I forgot Fortran, and was happy!

I had a class in C and FORTRAN in 87/88. I already knew FORTRAN, and I took it mostly for the C.
The teacher tortured us by assigning programs to be solved in the language least suited to solve the problem.
Write some numerical algorithm in C( not FORTRAN ).
Write some parsing and word counting code in FORTRAN(not C)
Kind of proved the point that you can solve any problem with any language.

Can we compare this with filling a round hole with a square peg? Only that the hole and peg are made of somewhat flexible rubbery material.

1971 1st year university Computer Science - FORTRAN IV on an IBM 360 with the WATFOR compiler which later became WATFIV. Punched cards and IBM golfball terminals.
Then onto IBM 370 then onto CDC 7000 series all with FORTRAN IV. All this mixed with COBOL, PL/1 and assembler.
Currently working with C# and thinking about learning Angular

I thought I'd need a card puncher to write true Fortran ...
(remembering that dangerous type of stack)
|
|
|
|
|
I have been writing Fortran since 1989 and have never used a punched card (or tape)
|
|
|
|
|
Around 1980 we had to use the puncher in my first Fortran class in the university.
Later I bought a Z80-PC with an 8" floppy - what a progress!

IBM 026 card punch machines and Olivetti teletypes producing blue paper tape where my starting point. Still have some original, unpunched, Fortran Statement cards kept as a souvenir.

I remember, when I studied at the Indian Institute of Science, in Bengaluru, India, in the early 90's, our lab had a big stack of (unpunched) punch cards. I have kept a few of them as a souvenir.

I remember having to modify someone's C who wrote mainly in Fortran. It was basically Fortran with C syntax. You can write Fortran in any language.
