| 41 | <p>The operation is used to create a parallel test component at any point in a behavior description by any other (running) component. | |
| 42 | <ul> | |
| 43 | <li>A component is created with its full set of ports and empty input queues;</li> | |
| 44 | <li>all component variables and timers are reset to their initial values (if any);</li> | |
| 45 | <li>the component itself is not started (the operation <a href="start.html"><b><font face="Courier New" color="#003258" size="4">start</font></b></a> is used to do this); </li> | |
| 46 | <li>the operation returns the unique component reference of the newly created instance.</li> | |
| 47 | </ul> | |
| 48 | <p>The optional <b><font face="Courier New" color="#003258" size="4">alive</font></b> keyword can be used to establish an "alive" parallel test component. | |
| 49 | <p>Optionally, a name can be associated with the newly created component instance. Associated component names can be free-format character strings, which are not required to be unique. | |
| 50 | <p>The main difference between normal and alive parallel test components is that alive parallel test components can be started many times while normal parallel test components can only be started | |
| 51 | once. See also the <a href="start.html"><b><font face="Courier New" color="#003258" size="4">start</font></b></a> keyword! | |

| 78 | <p><i>component_identifier</i> is a reference to an already defined component type. </p> | |

| 81 | <p>It may be optionally preceded by a <i> module_identifier</i> referencing the module where the component is to be created. The module identifier and the component identifier are connected by a | |
| 82 | dot.</p> | |

| 92 | <p>The first line declares a variable having the same type (CompType_CT) as the component to be created. The second line creates the component and stores its reference in the variable vc_CompRef.</p> | |

| 95 | <p><font face="Courier New">var CompType_CT vc_AliveCompRef;<br> | |
| 96 | vc_AliveCompRef := CompType_CT.create alive;</font> | |
| 97 | <p>The declared component reference (vc_AliveCompRef) will be used to store the reference of the newly created alive parallel test component.</p> | |
