Under what circumstances does the sender clause with receive etc. yield
an address, and under what circumstances does it yield a component? It
seems clear enough for system ports (address) and connected ports
(component). However, what does a mapped port yield - the system
component, or the address? (I'm assuming the address, but I'm not
sure.)

Dear Mike,

clause 6.2.12 Addressing entities inside the SUT.

The TSI is not a real test component, you cannot address it; the keyword system is used at port mapping only.

I know. But I can map a port that *is* part of a test component to a
system port, right? What is the value for the sender for messages
received on that port?

Hi,

"What is the value for the sender for messages received on that port?" -> You determine the value "manually" in the TTCN-3 code.

While the type of component references are not known (test-system specific) and the values are allocated by the test system implicitly and automatically (the user can/shall work with the variable names only), in case of address, both the type and the value are specified by the user (OK, there may be "tricky" cases, when the value is received from the adapter at some initialization phase and just stored in TTCN-3 - but it is just a specific use, it could be assigned by the user; the component reference cannot). E.g.

type charstring address;
const address you := "you";
...

mappedP.send(ts_myMessage) to you;
mappedP.receive(tr_myMessage) from you;

So I can get either the address, or the component by choosing an
appropriately typed variable, but not both?

Yes. Address is used on mapped ports _only_ and component references are used in to/from clauses of connected ports _only_.
