Help Center Help Center. Conditional statements enable you to select at run time which block of code to execute. The simplest conditional statement is an if statement. For example:. Alternatively, when you want to test for equality against a set of known values, use a switch statement. Each conditional statement requires the end keyword. In general, when you have many possible discrete, known values, switch statements are easier to read than if statements. However, you cannot test for inequality between switch and case values. For example, you cannot implement this type of condition with a switch :. Choose a web site to get translated content where available and see local events and offers.

Often we want to execute a command only if a certain test condition is satisfied. We use if statements to do this. If you want to execute certain commands only when a certain test condition is met, use a simple if statement of the form:. In myfile. In the example above, the test condition on the if statement was satisfied it was true since the value stored in x was indeed great than 4. Because the test condition was true, the statements inside the if were executed, and the final values of x and y after the if statement were different than the initial values. An if, else statement will allow you to execute certain commands if a test condition is true and execute other commands if the test condition is false. The commands inside the else are executed only if the test condition on the if statement is false. If the test condition on the if statement is true, the commands inside the if are executed, and the commands inside the else are skipped. Thus, only the commands inside the if or the commands inside the else will be executed, never both.
