Variable declaration

Value assignment

On the earlier versions of TOMB, the assignment of values to the variables used :=and that changed to only using the =V

Global variables

A global variable is declared outside any method and uses the keyword global so the compiler know's that variable is a global variable.

On the example below, you can see a declaration of a global variable of type number.

contract test {
    global myValue : number;
}

Local variables

A local variable needs to declared inside a method, and it uses the local keyword so the compiler know's that variable is a local variable.

On the example below, you can see a declarion of a local variable of type string;

contract test {
    public myMethod(){
        local myVariable : string = "something";
    }
}
