<td class="print-category">Description</td>
<td colspan="5" class="print">The section 21.3.2 on starting test
components doesn't say much about out and inout parameters. There's no
restriction on them, so they seem to be allowed. The only text
concerning these parameters can be found in the note 2: "Possible return
values of a function invoked in a start test component operation, i.e.
templates denoted by return keyword or inout and out parameters, have no
effect when the started test component terminates."<br />
<br />
There are several problems connected with that. The first problem is
obvious - this text should not be in the note as it has all attributes
of a mandatory rule.<br />
<br />
The second problem is related to the principle of passing inout
parameters by reference. This principle was introduced in recent
specifications and I think the implications on the start call were not
considered. Allowing to pass references this way would lead to shared
variables and I think this is not a desired effect. Ports, defaults and
timers are forbidden to be passed exactly for the same reason.<br />
<br />
In my opinion, it should be either completely disallowed to use inout
parameters in fuctions invoked in the start call (which is unfortunately
not a backwards compatible solution) or there should be a rule saying
that the actual inout parameters are passed by value in this case.<br />
<br />
The third problem is connected with the out parameters. Since the actual
parameter is not assigned when the test component terminates (as
described in the note 2), there's a question why the actual parameter
should be present at all. In my opinion, TTCN-3 should allow to skip
actual out parameters (see the related CR) and this notation can be
either recommended (in a note, backwards compatible) or mandatory (leads
to better code, but not backwards compatible).</td>
