Association of data objects
The presence of 'Association of Data Objects' in a tag indicates that it contains multiple subtags or objects represented in the following format: 2 characters for position, followed by 2 characters indicating the length of the value, and finally, the actual value.
For example:
Tag 30 indicates that it has a length of 23 characters.
Within tag 30, there is subtag 00 with a value of 19 positions.
Therefore, the 23 characters occupied by tag 30 are:
2 to indicate subtag 00 + 2 to indicate the length of subtag 00 (in this case, 19) + 19 for the value of subtag 00 (in this case, ar.com.globalgetnet)
