Used to inform the compiler that the programmer is happy that a call (usually communication) will use temporary memory. Some calls can not function without this and will give an error, others will work more efficiently with temporary memory but can operate without at a performance cost. This type is provided because often memory is at a premium, with applications running towards at their limit. It is therefore useful for the programmer to indicate whether or not using extra, temporary, memory is allowed.
