When an expression is required to evaluate to true or false (such as an IF-statement), a blank or zero result is considered false and all other results are considered true. Operators such as NOT/AND/OR/>/=/< automatically produce a true or false value: they yield 1 for true and 0 for false. A variable can be used to hold a false value simply by making it blank or assigning 0 to it. The words 'true' and 'false' are built-in variables containing 1 and 0. They can be used to make a script more readable. |
