Activity 13

Abstract

The manipulation of what are called strings in BASIC forms a very important part of the use of this language. String variables are distinguished from numeric variables by the addition of a dollar sign, $, after the variable name. String variables are different from numeric variables in the amount of storage they take up; string variables take up one byte per character, compared with numerical data which take up at least two bytes. In addition, a string variable can be any one of the characters available on your keyboard whether they be digits, letters of the alphabet or special characters. Numeric variables can only be, as the name implies, numbers.
