Any experts on pre-1970 #FORTRAN around?
The below two lines (there's stuff in between) are in IBM's SSP. It looks like it should be an out-of-bounds error, and in fact VS FORTRAN II refuses to compile it. So....???
DIMENSION XCOF(1),COF(1),ROOTR(1),ROOTI(1)
140 COF(2)=COF(2)+ALPHA*COF(1)
The Fortran Index hackathon is running online later today, 14:00 to 16:30. This session focusing on overhauling the fortran-lang package index. Still time to register, see www.cake.ac.uk/events/20260...

In the course of learning Python by writing a simple calendar converter, I came up with a wee library to work with rational data types (ie fractions) in Fortran:

It's not pretty and I would be surprised if it's best practice, but it seems to work […]

New #Fortran post: Improving the design of the test framework, part 2. matthiasnoback.nl/2026/02/fort... A module of 400 lines is too big. We're splitting it into smaller modules, and consider the benefits this provides.

Cover of Game Playing with Computers by Donald D. Spencer, revised second edition, featuring a bold red background with illustrated game elements including dice, playing cards, a chess rook, and a notebook with a tic-tac-toe sketch. The title appears in large white and red text, and the publisher “Hayden” is labeled at the bottom.
1790. GAME PLAYING WITH COMPUTERS

First published in 1968, this was a pioneering guide to coding games in FORTRAN (and some BASIC). Among the earliest books dedicated to "Video Games"

We find more good reasons for using custom derived types in the test framework. Assertion functions no longer print their results directly to screen. matthiasnoback.nl/2026/01/fort...
I predicted* in 2014 that #julialang might replace #Fortran for #science and #engineering calculations. I think this process has begun and will continue.

New #Fortran testing post: "Showing progress and printing results" matthiasnoback.nl/2026/01/fort... We introduce a polymorphic observer, so we can switch to a different way of producing output during a test run.

My goodness the weather in Ottery is hideous today (and has been all week). As my normal outdoor activities have been curtailed, I've started #AdventOfCode 2020 in #Fortran 77 (mostly). 11 days completed. Will I get to the end before the weather perks up?! #RetroComputing

New #Fortran blog post: "Unit tests and test suites" matthiasnoback.nl/2026/01/fort...
The next step towards a generic test framework is to let test modules announce their own tests to the test runner. We introduce the types unit_test_t and test_suite_t that carry procedure pointers.

New blog post about unit testing #Fortran programs: "Improving temporary test programs" Part 1 introduces assertions and an error counter. The series shows what the technical ingredients for a test framework are, and that they are quite easy to implement. matthiasnoback.nl/2026/01/fort...
