Activity 11

Abstract

This activity is about the use of lists of numbers held in the computer’s memory. A list is referred to by any valid variable name, and any item held in that list is located by a number in brackets after that variable name. For example, a list could be called by the name K, and K(7) would refer to the seventh item in that list. Every list has to be DIMensioned so that storage space can be reserved for it in RAM. Try the program listed in activity 11.1. The DIM statement reserves the number of locations to be allocated to the list specified by the number in brackets after the variable name. In this case the list A is to hold ten separate numbers referred to as A(1), A(2)…A(10).
