No but I did learn it for a ConPac 4020 process control machine with 4k of magnetic core and a paper-tape reader/punch To run a program you had to first load the FORTRAN compiler tape, then the program, the output being object code. Then load the linker tape and the object code, the output being an executable. Then load the operating system tape and the executable. Then press run. All to get the square root of 4, or something as trivial. All that now being useless knowledge. But the mathematics and theory behind numerical analysis/programming of second order non-linear differential equations means that I have a fundamental understanding of chaos and the dangers of predictive models which I don't think most economists and modern climate scientists have. -- Regards brd Bernard Robertson-Dunn Sydney Australia email: [email protected] web: www.drbrd.com web: www.problemsfirst.com Blog: www.problemsfirst.com/blog _______________________________________________ Link mailing list [email protected] http://mailman.anu.edu.au/mailman/listinfo/link
