| 32 | <h1>objid</h1> | |
| 33 | <p>The keyword bears multiple meanings: | |
| 34 | <ol> | |
| 35 | <li>Provides unique identification for TTCN-3 modules | |
| 36 | <li>Denotes the TTCN-3 predefined type for object identifier | |
| 37 | </ol> | |
| 38 | <hr align="left" width="50%"> | |
| 39 | <h3>1. Identification of TTCN-3 modules</h3> | |
| 40 | <p>A unique object identifier value may be assigned to each TTCN-3 module in order to distinguish e.g. different revisions of the implemented protocol specification. | |
| 41 | <p>This object identifier value may then be used in import statement to uniquely address the desired module. | |
| 42 | <p>Refer to keywords <a href="module.html"><b><font face="Courier New" color="#003258" size="4">module</font></b></a> and <a href="import.html"><b><font face="Courier New" color="#003258" | |
| 43 | size="4">import</font></b></a> for further details! | |
| 44 | <hr align="left" width="50%"> | |

| 67 | <h3>2. The <code>objid</code> predefined type</h3> | |
| 68 | <p>TTCN-3 offers the built-in object identifer type for storing object identifier values. | |

| 83 | <ul> | |
| 84 | <li>The <code>objid</code> can be used to type constants, module parameters, variables and templates. | |
| 85 | <li>The object identifier value itself starts with the <code>objid</code> keyword followed by the elements of the object identifier in curly braces. | |
| 86 | <li>Inside object identifier elements all formats (name, number and name-number form) are accepted. | |
| 87 | </ul> | |
| 88 | <hr align="left" width="25%"> | |
| 89 | <p>Example: | |
| 90 | <p><code> const objid c_etsiIN := objid { itu_t identified_organization etsi(0) inDomain(1) }<br> | |
| 91 | var objid v_etsiInIso := objid { iso identified_organization dod(6) internet(1) private(4) enterprise(1) etsi(13019) }<br> | |
| 92 | </code> | |
| 93 | <p>The above example defines an constant and a variable for holding an object identifier. Both are initialized with proper, reserved object identifier values. Inside the values one can observe the | |
| 94 | mixed use of elements. | |
