Sequence ({...})

To create an action that performs a sequence of other actions, the {...} operator is used - a block enclosed by curly brackets. The body of this block must contain a sequence of action operators and local property declarations.

Language

To declare an action that executes a sequence of other actions, use the {...} operator.

Examples

CLASS Currency;
name = DATA STRING[30] (Currency);
code = DATA INTEGER (Currency);

CLASS Order;
currency = DATA Currency (Order);
customer = DATA STRING[100] (Order);
copy 'Copy' (Order old)  {
    // an action is created that consists of the sequential execution of two actions
    NEW new = Order {                                   
        currency(new) <- currency(old); // a semicolon is put after each statement
        customer(new) <- customer(old);
    } // there is no semicolon in this line, because the operator ends in }
}

loadDefaultCurrency(ISTRING[30] name, INTEGER code)  {
    NEW c = Currency {
        name(c) <- name;
        code(c) <- code;
    }
}
run ()  {
    loadDefaultCurrency('USD', 866);
    loadDefaultCurrency('EUR', 1251);
}
