If... then... loop... return...
Yep done that, during my Electronics Engineering days at Manchester, you get your cards... and then drop them on the floor, and you have to sort them out again:doh
I hated Fortran, Basic was actually called a high level language at the time.
Just to add a few numbers, and find their average, took about twenty or more cards.
Talking of technology, my first Casio calculator had a glass tubed valve with green fluorescent digits, and two red hot wires that ran the width of the display.
You had to turn off the calculator between calculations, otherwise it wouldn't last for the whole lecture.
Happy days. It cost me £32 plus cases of AA batteries at the time, and my weeks part time wages were only £25
I remember my slide rule, still have it, there was always a problem, you got the right number, but it was often a factor of 10 out, since if you got to one end of the rule, you had to return to the other end, and continue the calculation, the problem was depending on which way you were going it was either x10 or divide by 10, I could never remember which was which.:doh :nenau
I bet anybody under 40 doesn't know what a slide rule is, unless they have seen one in a museum.:doh
