Ah, BASIC, I can understand (well not sure how much i remember now)! Many Many moons ago I did an O level at computing, we worked on Commodore Pets and had write a programme as part of the course. Slight digression, I did a simple database to identify criminal suspects by height, colour build crime committed etc. One of the 'known criminals' on the database was the computer teacher. For some reason, whenever we queried it he always seemed to to be the chief suspect!
