I remember dBASE IV from my childhood days when my father, who had no computer background, was required to take computer training by his workplace. My father and his colleagues were given free evening computer lessons by their company, taught by the same teachers who used to teach us, the kids, computers in our school. After their first class, he brought home a fat dBASE IV manual. Since I was very interested in computer books, I read a good portion of it even though I had never touched dBASE in my life. I would daydream of all the little forms, queries, reports and labels I could make with dBASE. But I never got to touch dBASE in my life. We kids used to get LOGO lessons instead in school. One day my father came back from his evening lesson mildly distressed about something he had learnt. He said they were being taught loops but in the loop there was an equation that seemed just plain wrong. It was: i = i + 1
How could that be a valid equation? How could i ever equal i + 1? He mentioned that he had asked the teacher about it and from what I could gather, my teacher and my father were talking past each other. The teacher probably tried explaining that it was not an equation but an instruction instead, whereas my father continued to interpret i = i + 1 as an equation due to the algebra he was so familiar with. It sort of held up the class for a while.The teacher asked my father's name, perhaps so that he could talk to him separately later. But when he learnt my father's name, he realised that his son, me, went to the same school where he taught. So he told my father, 'When you get back home, ask your son about i = i + 1. He will explain it to you better than I am able to.' And indeed I was able to explain it to him pretty well. I was eight or nine years old back then. And that was probably the first thing I taught my father! |
