Re: [Jolie-devel] OneWay messages

Hi Matthias,
this:
> twice( number ) {
>         result = number * 2;
>         println@Console( result )();
>     }
is not a construct in the language. Request-Response operations
support the { block } construct because it is useful to specify
something to happen *in-between* the request and the response. For
one-ways this is not necessary because they just receive something.
Hence you can just use the semicolon operator for expressing a
sequence and obtain what you want:

twice( number );
result = number * 2;
println@Console( result )()


Cheers,
Fabrizio.
