Hi Cathleen

I have always been good at Maths. Many years ago, I was a COBOL programmer. Also did ICL and JCL, plusFiletab 5 and 6 and Basic. That tells you how long ago I did this!!! It was a friend, who was a mathematician, who told me about the endless computer time on the square root of - 1. As a mathematician he used FORTRAN. He had access to a very large computer system. So, he asked it to calculate the square root of -1. It never stopped working, just trying to calculate something to which there is no answer.
