task
|
|
|
Tasks are identical to functions except they do not return a value. |
| |
|
|
|
|
task task_name (argument_list) {
statements;
}
|
| |
|
|
|
|
By default, tasks declared at the top level have a global scope. The local keyword is used to reduce the scope of a task to the file in which the task is declared. |
