Thus, an Intent(In) cannot be overwritten (at least locally, or even "globally" under some circumstances, see below). Similarly, Intent(Out) requires that the Arg be assigned an "explicit answer", thus helping to reduce "rubbish" results. WebIn a subroutine, an argument declared with INTENT (OUT) is supposed to hold a computation result so that its value can be passed "out". Finally, an argument can receive a value, use it for computation, and hold a result so that it can be passed back to the outside world. In this case, its intent is INTENT (INOUT) .
