40 | </li> | |
41 | <li> | |
42 | <p>address<br> | |
43 | is appended to the port type definition if the user wants to use <b><font face="Courier New"> address</font></b> values in TTCN–3 port operations.</p> | |
44 | </li> | |
45 | <li> | |
46 | <p>done<br> | |
47 | is appended to a function with <b><font face="Courier New"> runs</font></b> <b><font face="Courier New"> on</font></b> clause if the return value of that function must be retrieved | |
48 | after the corresponding component was stopped.</p> | |
