Computer Science without FORTRAN and COBOL is like birthday cake without ketchup and mustard.

:)
Used to teach Fortran 77 in the late 80's/early 90's. It was taught at that time as a Computer Science course though the biggest group of my students were studying Meteorology. I knew Fortran as an Electrical Engr undergrad, which I believe was the dominant group of people in the same class just a few years earlier. By the time I was teaching Fortran I was using C++ and APL for my work. A good APL programmer can write a program in one line, though nobody else will be able to read it.

That is an Infinite Do Loop.

Fortran bump.

I am too young to have had to implement Fortran using punch cards, but Fortran 77 was the second language I learned (learned MATLAB first), and then "moved on" to C++. Now that the newest incarnation of Fortran has interoperability with C and supports OOP, I may go back to it (in a way) to have access to all of the libraries.

RIP John Backus.

I will dim my monitor in his honor.

Former COBOL PL/I and 360 Assembler programmer.

I still use the backs of old "Hollerinth" (punch) cards for notes when I want to scare my co-workers.

The IBM 650 Magnetic Drum Calculator

****************************************EXCERPT****************************************

The 650 was a true general-purpose computer, the natural evolution of the CPC (Card Programmed Calculator) to a stored-program computer with a full set of decimal arithmetic, logical, and control instructions, plus (later) the ability to handle alphabetic data. It was initially programmed in machine language, then in SOAP (Symbolic Optimal Assembly Program), its native optimizing assembler (if "optimizing assembler" strikes you as an oxymoron, keep reading). SOAP was written in 1955 at Watson Lab by Stan Poley [65]; it was not the first assembler, but it was close (credit for that usually goes to Nat Rochester's assembler for the IBM 701 in 1954).

By 1957 a FORTRAN compiler (FORTRANSIT) was available (which compiled FORTRAN into SOAP; a native FORTRAN compiler appeared in 1959). (You will recall that FORTRAN itself was the child of Columbia University and Watson Lab alumnus John Backus.)

Where the heck do you get them? Or, have you carefully preserved a stash all these years?

I loved them for note taking. They were a convenient size, easy to carry around, made great book marks, etc. They also didn't curl, unlike lots of index cards one gets today.

I used to dream in FORTRAN.

Once had a vivid dream (nightmare) I still remember 20 years later. My job as a sysadmin was to keep a Microvax II running. (in real life) In my dream, if it went down, I was responsible for keeping the programs running. I had to read the fanfold paper and memorize the code, and then process it, verbally announcing each variable change. If a loop fell on a pagebreak, I had to repeatedly forget the other page and swap in the new page but still keep track of all variables. It went on all night. I think I had a fever.

Punch cards fit nicely in my suit vest pockets....I had a good supply when I retired but have run out of them.....

Do stand in the "dolt" corner then....

ROFL...Avirtual paging nightmare.....LOL!

RIP.

Excuse me I have to down to the center to see if my batch ran this time then put my 2000 fan fold pages through the burster.

I had a flashback to some excruciatingly long COBOL programs when I read your DO LOOP quip. Aack. Never did program in FORTRAN, did alot of COBOL.

[decimon]

i hated fortran!

I too long ago took a course in Basic and disliked it for the disconnect between the code and what it was doing. Then I took a course in Fortran and liked it for its making me know what the code was doing.

All posts in BNF, please.

BNF = Backus Normal (or Naur) Form.

Thank You....

I had a small, dwindling supply. Just a handful left now.
They'll go the way of all the reel-to-reel back-ups we have with no reel-to-reel tape reader!

My first IT job was actually typing in cobol pgms from cards into CICS/ICCF files. When I think back on it, I can't figure out why we couldn't import them from the cards??? Maybe it was just JCL?? Can't remember now....mind going....

I had a pair of gerbils when I was in college. I threw my used punch cards in their tank for them to use as bedding. They could turn dozens of cards to fluff in no time! (Also toilet paper and paper towel rolls, which the played in first then gnawed up.).

I remember students asking if it was alright to punch their COBOL pgms on the PL/I cards (we tried to keep them color coded).

The IBM 650 Magnetic Drum Calculator.....

This big iron picture brought back "fond" memories of the Burroughs D-880 I worked on in the 60's. Magnetic drums with their constantly crashing "flying" heads digging trenches in the surfaces, an hour of punched paper tape re-programming every time we lost power (often) and the no-break power system failed (always), and dozens of 4" muffin cooling fans that we oiled with hypodermic syringes. All this and about 8K of memory, or less, I don't exactly remember.
