Operators вЂ“ These are special symbols that are used for specific purpose. N, VAL1, AREA, G, PI etcвЂ¦ДЄlphanumeric Variables are used to store strings, these variables can also have a maximum length of 8 characters which can be both alphabets and numbers (must begin with an alphabet) but they must end with a $ sign. They can have a maximum length of 8 characters which can be both alphabets and numbers but they must begin with an alphabet and not a number. Numeric Variables can store only numeric constants. There are two types of variables in BASIC вЂ“ A variable must start with an alphabet and can be maximum 8 characters long. A variable allocates a space inside the physical memory of the computer (RAM) to store a value. The value of a variable can change during the execution of a program. Variables вЂ“ A variable is a memory location to store a constant. They may include alphabets, special characters, numbers or sentences. 656, вЂ“ 26, 3.14, 9.8, 0.0 etcвЂ¦ДЄlpha-Numeric Constants also known as String constants is a sequence of valid BASIC characters enclosed within a pair of double quotes. Numeric constants are numbers that can be either positive, negative or zero and can also be fractional numbers expressed with decimal point. There are two types of constants in GW-BASIC Those building blocks are вЂ“Д¬onstants вЂ“ A constant is a term or value that does not change during program execution. Just like any other programming language BASIC has certain building blocks which are used to develop programs.
