On alive components it is possible to execute several functions one after the other. Starting a function using the start statement on a PTC on which another function is executed already causes a runtime system error. Therefore the behaviour on the calling PTC has to check using the  running or done statements whether a new function can be started. <br />
<br />
It would ease the definition of the calling behaviour if the start statements for consecutive functions on one specific component could be written one after the other without intermittent done statements. To be meaningful, the function calls have to be queued, i.e. execution of the second function starts only once the first function has terminated.<br />
<br />
This can be achieved in different ways:<br />
a) change the existing semantics. Instead of causing a dynamic error if a new function is started, queue this function.<br />
b) Define a new type of PTCs, could be done similar to 'alive' in the create statement:<br />
ptc.create queueing<br />
c) extend the start function statement by a directive to indicate that the function is to be queued.<br />
ptc.start(f(), queueing);<br />
d) allow to consider a TTCN-3 function as a TTCN-3 procedure that can be called in a call statement. To avoid that the code to accept the call has to be written manually, a new kind of component or a specific behaviour is needed that accepts such function calls and executes the corresponding functions.<br />
<br />
The alternatives have different advantages. These and further detail regarding d) are provided in the (yet to be) attached document.</td></tr><tr class="print"><td class="print-category">Steps To Reproduce</td><td class="print" colspan="5"></td></tr><tr class="print"><td class="print-category">Additional Information</td><td class="print" colspan="5">Applies also to edition 3.3<br />
