In The Emperor's Old Clothes Tony Hoare mentions his work on implementing " a library subroutine for a new fast method of internal sorting just invented by Shell."

Here is the manual page for that subroutine : http://www.peteronion.org.uk/803Documentation/803D2.pdf

Cool. Over nine minutes to sort 4000 integers !

Paul Webster,

Wow, it's a long time since I heard anything from a former Coral-66 programmer.

I did a couple of years of Coral 66 back in the early 1980's. For Marconi Radar.

Yes, Coral was similar enough to Algol to be picked up quickly. I had never heard of it before starting at Marconi Radar. They took me on as a contractor anyway. Didn't get any training in Coral either. Just had to wing it based on my experience of Algol back in uni.
Hey, neighbour! I was on the next floor at GEC (assuming you were at Marconi in Borehamwood?) 1981-1983 roughly.

I wrote one program in Coral and after that everything was in Pascal. OH!! Except for ... TA DA!!! ... Babbage!

I had forgotten about Babbage until now. Another UK programming language. Or possibly assembler, depending on how you looked at it.

If i remember rightly, I wrote GEC's first screen editor in Babbage. They were paranoid about the amount of CPU it took to do single character interaction so I designed an editor that took advantage of the buffered mode of the (Hazeltine?) terminals and was as efficient as a line editor.

Probably the only useful contribution I ever made to that company ;-)

gtoal,

No. 1980 to 1983, or thereabouts I was at the Marconi Radar R&D labs in Great Baddow. A few years later I did two years as a contractor at Marconi Radar, Writtle Rd, Chelmsford. That's where the Coral 66 thing happened. Developed on whatever GEC mainframe and targeted at the Marconi Locus 16 mini/embedded computer. http://www.computinghistory.org.uk/det/ ... -Locus-16/ For the Martello 713 3D radar: http://marconiradarhistory.pbworks.com/ ... st-Marconi

Later again I contracted for Marconi Secure systems in Liverpool. Coral was history by then. Ada had taken over.

Here is a British programming language https://en.wikipedia.org/wiki/Occam-%CF%80
