| - | ====== Jump statement ====== | ||
| - | The **jump** statement transfers the control to the line of code identified with the **label**. | ||
| - | |||
| - | **Labels** in Alvis are identifiers followed by a colon. A **label** must start with a lower case letter. | ||
| - | |||
| - | It is necessary to put at least one statement after a label. In other words, a label cannot be followed by a closing curly bracket. | ||
| - | |||
| - | The **jump** statement is a single-step statement. | ||
| - | |||
| - | The **jump** statement should be used carefully, e.g. you cannot jump from one procedure to another. | ||
